✈️ The Maddening Mess of Airport Codes! ✈️
Summary
TLDRThis video script delves into the world of airport codes, managed by the International Air Transport Association (IATA). It explains how three-letter codes ensure unambiguous travel worldwide, with unique codes for each airport despite potential name overlaps. The script humorously explores the quirks and history behind these codes, including country-specific preferences and exceptions, such as Canada's use of 'Y' codes. It also touches on the role of IATA codes in baggage handling and the contrast with the four-letter codes used by the International Civil Aviation Organization (ICAO) for a broader range of aerodromes.
Takeaways
- 🌐 IATA airport codes are three-letter codes used to uniquely identify airports worldwide for easy and unambiguous communication.
- 📍 The IATA codes are managed by the International Air Transport Association (IATA), which is headquartered in Montreal, Canada.
- 🔤 IATA codes are derived from the first three letters of an airport's location, but there are exceptions due to various reasons including prior claims by other airports.
- 📚 Canada claims the 'Y' codes, which is a unique pattern in IATA coding, possibly due to historical radio call sign conventions.
- ✈️ FAA in the United States assigns three-letter codes to American airports, with certain letters like 'N', 'Q', 'K', 'W', and 'Z' being avoided for various reasons.
- 🌍 The ICAO, a UN agency, uses four-letter codes to identify airports, including smaller aerodromes, and incorporates location information into the codes.
- 🔄 There are 'Mega codes' for mega cities with multiple airports, like London's 'LON', which can be used for searching flights to any of London's airports.
- 🏭 Some airports have more than one code, especially in cases of international collaborations or unique logistical arrangements.
- 🛅 IATA codes are crucial for baggage handling, ensuring that bags are routed correctly through various airports and countries.
- 📝 The history of airport codes is deeply rooted in older systems like radio call signs and telegraph codes, reflecting a century of aviation and communication evolution.
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.

🌍 Airport Codes: The Global Language of Aviation
This paragraph discusses the importance of airport codes in the aviation industry. These three-letter codes, assigned by the International Air Transport Association (IATA), are crucial for clear communication and efficient baggage handling across different languages and countries. The script explains the origin of these codes, their purpose in avoiding confusion caused by similar-sounding airport names, and the role of IATA in maintaining a standardized system. It also touches on the challenges of assigning unique codes to every airport and the process of managing code collisions.
🇺🇸 FAA and IATA: The Complexities of Airport Code Assignment
The second paragraph delves into the intricacies of airport code assignment by the Federal Aviation Administration (FAA) in the United States. It highlights how FAA avoids certain letters like 'Q' and 'N' due to their use in other systems, such as Morse code and the Navy's system. The paragraph also discusses the existence of 'mega codes' for cities with multiple airports, like London's 'LON', and the exceptions to the FAA's guidelines, such as airports that start with 'K', 'W', and 'Z'. The narrative emphasizes the lack of a systematic approach to airport codes due to various national preferences and the role of IATA in coordinating these codes.
📚 The History and Evolution of Airport Codes
This section explores the historical background of airport codes, explaining how the IATA and ICAO (International Civil Aviation Organization) systems differ. It outlines ICAO's use of four-letter codes that include geographical information, in contrast to IATA's three-letter codes. The paragraph also discusses the origins of the codes, tracing back to the ITU's radio station codes from the 1910s. Additionally, it mentions the exceptions to the ICAO system, such as Antarctica's pseudo codes and the unique situation of EuroAirport Basel-Mulhouse-Freiburg, which has three different codes.
🎉 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.

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
FAQ OMG LOL
