Q & A

What is the purpose of airport codes?

Airport codes, assigned by the International Air Transport Association (IATA), are three-letter codes used to uniquely identify airports worldwide, facilitating clear communication and efficient handling of passengers and their luggage across different airlines and countries.

Why are IATA airport codes important for passengers and airlines?

IATA codes are crucial for avoiding confusion caused by similar or identical airport names in different locations. They provide a standardized, unambiguous way to refer to airports, which is essential for booking tickets, tracking flights, and ensuring that passengers and their luggage are routed correctly.

How does the IATA generate airport codes?

Typically, IATA codes are derived from the first three letters of the airport's location. However, due to various factors such as existing codes and regional preferences, this is not always the case, leading to some variation and the need for coordination by the IATA.

Why do some Canadian airports have 'Y' codes?

The use of 'Y' codes for Canadian airports is believed to be a legacy system from when 'Y' indicated the presence of a weather station ('Y' for 'Yes', 'W' for 'Weather'). This practice has continued due to historical precedence and coordination between the U.S. and Canada for flight within North America.

What is the role of the FAA in assigning airport codes in the United States?

The Federal Aviation Administration (FAA) is responsible for assigning three-letter airport codes in the United States. However, it tends to avoid certain letters due to various reasons, such as Morse code considerations, existing usage by other agencies, or historical practices.

How does the IATA handle situations where an airport code might be ambiguous or already taken?

When an airport code is already taken or might be ambiguous, the IATA coordinates with aviation agencies and airports to find a suitable, unique code. This can result in airports having codes that do not directly reflect their names or locations.

What is the significance of 'Mega codes' in IATA's system?

Mega codes are used for cities with multiple international airports, such as London's 'LON'. These codes allow passengers to search for flights to a city without specifying which airport, simplifying the booking process.

Why do some airports have more than one IATA code?

Some airports have more than one IATA code due to historical reasons, shared operations with another country, or because they are part of a larger airport system. An example is EuroAirport Basel-Mulhouse-Freiburg, which has three different codes depending on the country of departure.

What is the difference between IATA codes and ICAO codes?

IATA codes are three-letter location codes used primarily for commercial airports and airline operations, while ICAO codes are four-letter codes that include a wider range of aerodromes, such as small airports and airstrips. ICAO codes also incorporate location information into the code itself.

How does the IATA's system of airport codes affect the handling of luggage?

The IATA codes are critical for the efficient handling of luggage. They are used on baggage tags to ensure that bags are routed correctly through various airports and countries, minimizing the risk of misrouting.

🎉 The Fun Side of Airport Codes: Branding and Memorable Codes

The final paragraph brings a lighter note to the discussion by highlighting the branding potential of airport codes. It mentions how some airports have embraced their codes for marketing purposes, such as YSU (Sudbury Airport), which uses the tagline 'Yes, you can!'. The paragraph also humorously lists some of the more amusing or memorable codes, like 'FAQ' for Fort Lauderdale or 'LOL' for Gillette–Campbell County Airport, showcasing the quirky side of aviation codes.

Keywords

💡IATA

IATA stands for the International Air Transport Association, which is a trade association of the world's airlines. In the context of the video, IATA is responsible for assigning three-letter airport codes that uniquely identify airports worldwide. These codes are crucial for simplifying the process of air travel and ensuring that there is no ambiguity when booking flights or tracking luggage. The script mentions that IATA codes are part of the planning on tickets, trackers, and tags, highlighting their importance in the aviation industry.

💡Airport Codes

Airport codes are three-letter location identifiers assigned by IATA to airports worldwide. The video emphasizes the role of these codes in reducing ambiguity in air travel, especially when airport names might be shared across different locations. For example, the script mentions 'booking passage to Portland' which could refer to multiple cities, hence the need for unique codes like 'PDX' for Portland, Oregon.

💡Interoperability

Interoperability refers to the ability of different systems and organizations to work together seamlessly. In the video, it is mentioned in relation to the role of IATA in making airports and airplanes work together efficiently. The script describes how IATA uses standards such as the three-letter airport codes to facilitate clear communication between airlines and airports.

💡Mega Codes

Mega codes are unique IATA codes assigned to large cities with multiple airports. The video explains that these codes encompass all airports within a city, allowing passengers to search for flights to a city without specifying the airport. An example from the script is 'LON' for London, which can be used to search for flights to any of London's six international airports.

💡ICAO

ICAO stands for the International Civil Aviation Organization, a UN agency that sets standards and regulations for international flight. The video contrasts IATA and ICAO, noting that while IATA focuses on commercial airports, ICAO covers a broader range of aerodromes, including smaller airfields. ICAO uses four-letter codes that include location information, unlike the three-letter IATA codes.

💡Checksum

A checksum is a form of redundancy check used in error detection. In the context of the video, it is mentioned that IATA codes do not have a checksum letter, which could potentially lead to confusion or errors when typing codes. For example, 'CGP' for an airport in Bangladesh and 'CPG' for an airport in Argentina are very similar and a typo could result in a wrong destination.

💡Telegraph Slang

Telegraph slang refers to the use of abbreviations in telegraph communications, which dates back to the 1800s. The video mentions that some letters, like 'Q', are avoided in FAA codes due to their use in international Morse code for quick communication, a legacy from telegraph era practices.

💡Branding

Branding in the video refers to the use of airport codes as part of the identity and marketing of airports. It is mentioned that some airports have embraced their codes for branding purposes, such as the airport with the code 'SUX', which humorously owns its branding despite the potential for negative connotations.

💡Canada's Y Codes

The video discusses a peculiarity of Canadian airport codes, many of which start with 'Y'. It explores the possible origins of this pattern, suggesting it might relate to old weather station codes. The script notes that while this pattern is not entirely consistent, it is a notable characteristic of Canadian airport codes.

💡Intermodal

Intermodal refers to transportation systems that allow for the use of multiple modes of transport in a single journey. The video uses Amsterdam Schiphol as an example of an intermodal airport, where plane stations connect to train stations. The script praises the efficiency of such infrastructure.

Transcripts

there are thousands of airports

connecting cities across countries and

continents yet with just three letters

from AAC and BBI to YYZ and zzu both me

and you and our bags root round the

world as unambiguously as practically

possible airport codes if you fly you

know them as part of the planning on

your tickets trackers and tags and even

as part of the port itself as big big

branding it's impossible not to wonder

bored on a long haul with only in-flight

entertainment about potential patterns

peeking through like all the Canadian y

airports why Canada and why everyone how

do all these codes code well neighbor to

find the answer we need to divert this

flight to Yul the Canadian city that's

capital of codes Montreal where is

headquartered ayata the International

Air transport Association it's not a

governmental organization more an

independent Aviation Agency for Airlines

where they work to make airports and

airplanes increasingly interoperable

using Humanity's most exciting and

Powerful yet off-maligned as dull tool

standards one of which is the iata

airport code three letters to identify

every airport in the world from the most

connected to the least all are coded so

companies can communicate clearly and

concisely complicated connections to

carry their customers and their bags and

actually the code I had to created isn't

only for airports rather technically

it's a location code for all kinds of

Transportation interchanges like plane

stations that connect to train stations

such as Amsterdam shippo which is just

so intermodally epic okay let's try not

to get distracted by efficient

infrastructure easier said than done

here's how the iata code is supposed to

work one airport one code which is

unique because airport names are not

booking passage to Portland cool that

could be Oregon or Maine or Victoria

Australia ambiguity is the enemy

International flying creates

communication connections between every

language on Earth so the iata code helps

when you don't speak greenlandic or odia

but still need to book a flight to

kangarless Sac via Bob bainsware I'm so

sorry Greenland in India instead of

mongoling pronunciation it's just sfj

via BBI much clearer not just for you

but also for the ground crew getting the

bags through ideally the iatic code

comes from the first three letters of

the location like with Gibraltar where

Gibraltar airport is given gib gib

Gibraltar so going to Cork it'll be

c-o-r core Ireland oh that didn't work

seems Cordoba Argentina built their

airport first and got cor ahead of Quark

so uh orc for cork tough noogies orc

Germany that's an adorable Town name

you've got there but you're going to

need to pick something else for your

code thus a single code Collision kicks

off a consistency Cascade as airports

compete for clear codes so if your local

airport has an odd three letters there's

probably a rival Port that picked

previously this is one of the major

things I added does coordinate

everyone's code preferences which means

dealing with not just individual

airports but all the aviation agencies

in different countries some with their

own design desires for inter-country

code consistency such as Canada who

clearly claimed all the whys thus

picking a y1 at random at least you know

roughly where you're going to go oops no

that didn't work why km brought us to

Washington USA and since we're here we

might as well talk about the FAA in

America the Federal Aviation

Administration daughter of the

Department of Transportation is given

the job of assigning All American

airports and American airport code yes

the FAA actually has her own set of

three-letter codes but we're not going

to talk about it because it means in

America there's one airport two codes

and for Simplicity I'm sticking to this

story one airport one code right right

now FAA has letters she'd really rather

American airports not please know

nqwkz or y n is reserved for the Navy

for OMG is it aircraft carriers no they

use an unrelated and additional system

that we're also not going to talk about

the Navy n is given to Navy bases with

air airports so American airports like

Nashville that seem like they should

start with the letter N were encouraged

to pick something else like B for but

Asheville there is also a for the Army

and the Air Force although not all the

A's so there's a bunch of a airports

like Albuquerque Aberdeen Anchorage

Amarillo and Augusta next qfaa Once

avoided because of checks notes Morse

code wow really there's a set of three

letter International Morse codes that

begin with Q for quickie Communications

that are still used I guess so because

of 1800s Telegraph slang American

airports shouldn't start with the letter

Q next K and WFAA advises against

because FCC the Federal Communications

Commission daughter of no one she's an

independent agency assigns K and W for

U.S civilian broadcast stations so that

thing where on the radio they say kmad

Action News or wdul public Airwaves yeah

they all start with a k or W which is

actually location information k days are

in the west and W's in the East except

for the Middle where it's both FCC why

did you do it this way well since you

coded those codes first FAA discourages

airports from starting with those

letters even though broadcast codes are

four letters not three and there you

know radio stations not airports and

definitely not weather stations of

course they're not weather stations why

would you even say that no reason it

won't come up later don't worry moving

on Z is reserved for air Route traffic

control centers themselves and why know

why because Canada of course yes I

understand that's not an explanation

we'll get to it later that's America's

preferences for airport codes but other

countries exist and their Aviation

agencies don't care at all which letters

the United States avoids so while

banashville was building her big big

branding Nassau grabbed the end to get

Nas for the Bahamian Capital there's no

shortage of airport codes that start

outside the US with America's reluctant

letters and also because faa's

precedence aren't laws you can find

American exceptions like new kekwa yak

quig and ziv boy that was fun to say

let's end the video with more of that

shall we and that new must particularly

burn Newark New Jersey who had to go

with urk u Jersey instead right

finishing this thought every country and

their agencies has their own wacky

preferences for letters and wants to

ignore every other country's preferences

and ayada's job is to coordinate between

them the result of which is ayata

airport codes have no satisfying system

at all which is so sad for a standard

and the story of one airport one code

also falls apart even within ayata

because of Mega codes for mega cities

example London which has six

international airports Heathrow Gatwick

City Luton stance at South End lhr lgw

lcy ltn oh they all start with l no stn

s-e-n but there's a mega code for them

all l-o-n which you can use while

searching for flights landing in London

but don't care where even though these

airports are ages apart Lon is the

international City megaist Mega code but

there's also Moscow mow and Stockholm

sto with four airports each and more

with two or three like NYC and bue and

then code wise is the most exceptional

airport Euro airport basil Mall house

Freiburg an airport so nice they coated

its Thrice mlhbsl EAP how this happened

is France and Switzerland both wanted an

airport here ish near the German border

and teamed up France provided the land

Switzerland the capital Germany has

nothing to do with this and the pair

co-built the port constructing duplicate

and separate everythings so it was

effectively two airports run by two

countries with two runways and two sets

of rules and thus needed two airport

codes depending on which side passengers

could connect through and one Mega code

if it didn't matter but all of this

doesn't Mega matter now because the two

airports mostly act as one anyway thus

one airport three codes and there are

plans to run a railway through for epic

intermodleness so it could become one

airport four codes or five codes I mean

why not at this point so yeah an airport

isn't uniquely identified by one code

and there's no location information

coded in this location code not even a

checksum letter what is this a social

security number without a checksum if

you are planning a flight to cgp airport

in Bangladesh but typo the incorrect cpg

you'll end up in Argentina instead again

but at least the chance of a Switcheroo

like that must be pretty small after all

a three-letter code means 17 000

permutations way more than the actual

number of airports which is only 40

000 airports worldwide how can that

possibly be true well it's time to

introduce you to Iko the international

civil aviation organization daughter of

the United Nations who also lives in

Montreal with ayata and it might seem

like they're the same but ayata actually

only covers what we might call the

standard commercial airports you'd find

searching for flights normally while Iko

covers what she calls aerodromes which

is everything from the world's busiest

passenger airport in the always unlikely

seeming Atlanta Georgia down two rarely

used runways on ranches in Texas of

which there are an absolutely absurd

number so with all those aerodromes to

account for Iko uses four letters which

gives wow a lot more options thanks

exponentials and she also uses the extra

space to add location information

finally in IKEA system the first letter

of an airport code is roughly where on

Earth it is P is for airports in the

Pacific one letter to cover flying over

the most terrifyingly empty half of the

earth try not to think about it as you

look down into the endless Abyss before

arriving at South America s then M for

Middle America and K for Continental

America C sensibly is Canadian America

and flying over the pole we get to you

for used to be USSR yes that's actually

the name look what makes standard

standard is their stubbornness just

because a gigantic country collapsed is

no reason to change what millions of

flight computers know in their code and

pilots in their brains after iko's first

letter there's also a bunch of second

subletters well except for America and

Canada who Skip that but don't worry

moving on as an example if your airport

starts with an F it's in southern Africa

and if the next letter is a that's South

Africa and the last two letters are for

the airport so Cape Town gets CT for a

fact of course there are some exceptions

like Antarctica the continents no one

owns but all the cool kids want to claim

aerodromes here are supposed to use the

code for the countries claim they're in

such as Williams Field which is American

run but uses nzwd because it's in the

Kiwi claim but also lots of Antarctic

aerodromes use pseudo codes no we're not

going to talk about what that means

which start with a t and end with a

number like 27 for troll Airfield

serving troll research station which

runs on troll time Norway is that you I

knew it was but you really should be

using en for Europe Norway and TR is

free enter trolls it's so perfect and

yes the 27 means there are at least 26

other runways in Antarctica I was

surprised too but this along with all of

the ranches is how you get to crazy

numbers of aerodromes and yes Iko has

more exceptions to this system that

we're going to skip but I can't resist

just one more which is region J looking

at the map you won't be able to find it

because Jay is Mars when the Rover

arrived at jazeero Crater Iko gave the

historic Landing location the code jzro

okay but that's it for exceptions so to

sum up the story of one airport one code

was just that a story tons of airports

have at least two and when they do the

Iko code is what computers and Pilots

know to plan where the plane needs to go

and ayada is what passengers say to get

on their way but if Iko exists with a

more comprehensive code why is ayata at

all so ayada is isn't about you it's

about your bags at an airport you as a

human walk to your connecting flight but

your bags below need a lot of logistical

assistance before ayata there was just

like a handwritten tag saying please get

me where my owner is going written in

potentially every language on Earth so

you can imagine how often that went

wrong so I added used codes to make life

better for bags with bag tags with big

clear codes to get those bags cleanly

through connections across countries and

companies and the original plan was that

train stations with iata codes would

also let you check in your bag there and

it would be part of the automatic

connection too but that mostly doesn't

happen now because of logistical

difficulties which is the same reason

that the iatic code is a club that

excludes all the little aerodromes to

annoying to attend to so if your bag's

Final Destination after connecting at

Austin is one of the many random Ranch

airstrips the ground crew is not going

to to swap your bags onto the tiny crop

duster for you ditto if you're

connecting through Argentina to

Antarctica anywhere those tiny airports

know I had a code for you and without an

iata code your bag depends on you to get

it all the way through and that's what I

Adda is actually for that's big big

branding you see is for your bags and

because of the tag it became what

customers know which brings us back to

the start and oh sorry Canada I know

I've been avoiding answering the whys

but it's just so much more complicated

than expected there's a tale that the

Y's are an old system for if Canadian

airports had a weather station why for

yes weather station and W without and

since Pilots want to know the weather

that explains all the whys but also the

few Oddball Canadian W's but

investigating the truth of that story

took eight months of my life which I

will now give to you as an extremely

compressed executive summary working

backwards the American and Canadian iata

codes created in the 1950s come from the

last three letters of Iko codes created

in the 1940s the first letter of Iko

codes come from the itu the

international telecommunications Union's

codes created in the 1910s for radio

stations which used k for America and Cy

for Canada so K and Cy into four letters

and back down to three leaves y for

Canada here is where you would

reasonably ask why Cy for Canada but

that goes all the way back to telegraphs

and Beyond so is a story for another

time but for now for this video YY for

Canada because of radio call signs

because of a lot of other things because

of U.S and Canada coordinating that four

flights within North America it really

would be why for yes Canada mostly well

that was a lot of bureaucratic history

so let's finish with the final fun Iota

codes promised from before starting with

city with a sensible looking sux until

you say it out loud but to her credit

totally owns that branding for airport

merch good for you Sue and there's also

Beach's International Airport summer

break Central their top two picks for

codes were picked so to help the uh

confused Collegiates find their

connections the agencies agreed on ECP

to stand for everyone can party which is

awesome branding but you'd never know

because beaches doesn't bother geez ECP

you could learn a thing or two from Sue

but now everyone can party on this round

the world flight of iata codes

entertaining to say out loud ready Fab

boo eek cow wow poo gag bro butts got

hot pie yum um mom dad mad Run fun IOU
