Initial comments

Should note that three-letter location codes in the United States are set by the FAA (and likely similarly in other countries by their regulatory agencies) and not by IATA. However, the code assignments are usually coordinated to reduce confusion (i.e., IATA codes are usually not duplicated by FAA codes, but not all three-letter FAA codes are also IATA codes). There are also four-letter codes (different from four-letter ICAO codes); the form of the location code is determined by its status and level of activity. See FAAO 7350.7K for more details. 18.24.0.120 03:16, 14 Dec 2003 (UTC)

The codes do not seem to be alphanumeric, merely alphabetical. I can see why 1,0 would want to be avoided, but 2-9 could be used. 26^3 means there are only 17576 possible codes, so with 20000 airports there are more than 323 overlaps? Any examples of the codes that do overlap? --/Mat 15:52, 13 Mar 2004 (UTC)

Perhaps CBG is one, in practice at least: in the US it's largely used to represent Cambridge, Minnesota although IATA seems only to have allocated it to Cambridge, England. See my note at Talk:List_of_airports:_C for examples. Marnanel 00:08, Apr 11, 2004 (UTC)

dead link

Burgundavia reverted my edit of the external link

http://www.world-airport-codes.com/

yesterday as well as today I tried to acess this URL, from different computers. I always got the following error message:

The requested URL could not be retrieved

While trying to retrieve the URL: http://www.world-airport-codes.com/

The following error was encountered:

Unable to determine IP address from host name for www.world-airport-codes.com The dnsserver returned:

Server Failure: The name server was unable to process this query. This means that:

The cache was not able to resolve the hostname presented in the URL. 
Check if the address is correct.

Does this qualify for my statement on the wikipedia page that the link is dead???

This seems like a local dns issue with you, as I can access the website fine. Burgundavia (✈ take a flight?) 10:21, May 19, 2005 (UTC)

Agree, works fine for me. Bollar 15:56, May 19, 2005 (UTC)

I found that the link in the reference section give a "Page Not Found. Sorry, the page you have requested cannot be found on www.iata.org" error message. The dead link is http://www.iata.org/whatwedo/aircraft_operations/coding/index.htm There is a similar link which does work: http://www.iata.org/whatwedo./aircraft_operations/codes/index.htm

The problem with the corrected link is that it provides Airline codes (Airline = companies operating aircraft.) For a list of the IATA airport codes the list can be obtained here: http://www.iata.org/ps/publications/ccd

Hopefully someone will sort this out as to what links should be cited in the main article.

Chicago O'Hare

The article on Airport ABC's incorrectly states that Chicago O'Hare (ORD) was originally named Orchard Field. It was originally named Orchard Depot.

http://www.ipsn.org/ohare.html

Actually it was called Orchard Field (FlyChicago's Official Website). Dbinder 13:57, 20 January 2006 (UTC)[reply]

Canadian airports

Question Can anyone explain how and why Canadian airports got stuck with the Y prefix? Steelium 3:05, 19 February 2006 (UTC)

For some incomprehensible reason, the Diefenbaker government (1957-1963) agreed to have all Canadian airports start with Y. I don't know, maybe Dief's people wanted a single prefix letter for all of Canada and most of the Ys were unused?

Myself, I think IATA codes should be expanded to five characters by prefixing the two-character country code, e.g. YVR Vancouver would become CAYVR. This would eliminate duplication, and allow countries to choose IATA codes that more closely resemble the airport's identity, e.g. CALBP (or CATPA) for Lester B. Pearson Intl Airport in Toronto, CAPET (or CAMPT) for Montreal's Pierre Trudeau Intl Airport. It would also allow 17,576, (13,824 if I and O are not included) combinations per country, more than enough for all the airports, train stations, helicopter ports, etc. It would also provide standardized recognition of the country name.

IATA codes are officially 5 character, but most only use the three character version. When I worked on airline flight operations software, the database and all software was designed to be 5 character aware and the plan, as explained at the time, was that IATA would roll out the 5 character version in the future. I guess we're still waiting.

By the same token, the airline codes are officially 3 character, but most only use two. Michael Daly 06:12, 5 May 2007 (UTC)[reply]

BTW - not all Canadian station codes begin with Y. There are a few obscure ones that have other letters, but I can't remember one offhand. Michael Daly 22:42, 21 May 2007 (UTC)[reply]

Mississippi airport

I agree, we are a new airport in Mississippi (Tunica) and our FAA ICAO code changed to KUTA or just UTA in the states, we tried to use UTA for our IATA code and it is already taken (in Zimbabwe). We were forced to use UTM for IATA code beacuse it was already taken. —The preceding unsigned comment was added by 137.14.10.22 (talk) 01:53, 30 January 2007 (UTC).[reply]

City codes covering multiple airports

Should the article say something about these codes (e.g. LON, PAR, NYC)? I'm not sure how many of them exist, but I recall from somewhere that IATA decided to stop issuing them several decades ago. Grover Snodd (talk) 15:22, 19 July 2009 (UTC)[reply]

I think it should -- in fact I came here looking for information about this. --81.178.31.210 (talk) —Preceding undated comment added 15:18, 6 December 2011 (UTC).[reply]

The article mentions that, with good examples. Maybe a more comprehensive list is in order201.87.57.72 (talk) 02:56, 7 June 2013 (UTC)[reply]

IATA codes used elsewhere?

Are IATA codes used by US or European bus lines? or passenger cruise ship lines? LanceBarber (talk) 04:44, 22 August 2009 (UTC)[reply]

TYS

In the weird codes paragraph, the TYS (Knoxville) is probably because of Tyson in its name. I am not deleting it though, please discuss whether it should be removed from the list. — Preceding unsigned comment added by WikiRigby (talk • contribs) 23:03, 6 March 2012 (UTC)[reply]

I found out that most are named after individuals, so never mind. ~WikiRigby ^talk_sign! 23:06, 6 March 2012 (UTC)[reply]

List of city codes

Feature request: it would be nice if the list of airport codes http://en.wikipedia.org/wiki/List_of_airports_by_IATA_code:_N had a sublist for "city codes" such as NYC and BER. I.E one code for multiple airports. 79.181.180.169 (talk) 14:48, 18 February 2013 (UTC)[reply]
