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)
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:

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??? — Preceding unsigned comment added by Abarenbo ( talk • contribs) 07:50, 19 May 2005
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.

The article on Airport ABC's incorrectly states that Chicago O'Hare (ORD) was originally named Orchard Field. It was originally named Orchard Depot. — Preceding unsigned comment added by 68.218.136.185 ( talk • contribs) 11:09, 27 May 2005

Question Can anyone explain how and why Canadian airports got stuck with the Y prefix? Steelium 3:05, 19 February 2006 (UTC)
I was told they were based on some sort of railway code? — Preceding unsigned comment added by 198.90.95.165 ( talk • contribs) 20:43, 7 August 2015
There are now two sections where Canadian airport codes are explained. Unfortunately they say subtly different things - one is "Yes, there's an airport at the weather station" and one is "Yes, there's a weather station on the railway". Noting that here since I don't have time to fix it - please could someone do some research and establish what the accurate explanation is? Dichohecho ( talk) 13:06, 2 October 2017 (UTC)
I do not at all believe the explanation "Y is for Yes, W is for Without" - the source is some arbitrary blog. I haven't been able to find corroborating evidence for any of the explanation offered in the article, so I have added a citation needed and an unreliable source tag.
I would be more likely to believe some explanation about radio call-signs or something. At least that would match up with ICAO codes (which are generally just IATA codes with an extra C at the beginning for most airports). But I wasn't able to find any corroborating evidence for that either. I spent 3 hours trying to find something haha... Hope someone can shed some properly-referenced light on this mystery.

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

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)
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)
This entry is quite US-centric. Would it make sense to divide into regions more clearly ? — Preceding unsigned comment added by 198.90.95.165 ( talk • contribs) 20:44, 7 August 2015
This is probably WP:OR without a source, but I'd like to see some discussion about how airports create marketing slogans around their IATA codes. The three examples I have in mind are all somewhat non-intuitive codes for their respective cities, which I suspect is not a coincidence—the marketing push could also help create mnemonics for remembering the codes. Orlando Sanford and Spokane use "Simpler, Faster, Better" and "Generating Economic Growth", respectively, in marketing. Norfolk uses "Take ORF" (which I've always assumed to be a play on "Take off"). -- BDD ( talk) 19:36, 8 January 2016 (UTC)
The history and conventions section says the following:
It then proceeds to give "EWR for Newark" as an example of the latter. However, it then continues on by saying
But it gives "HNL for Honolulu" as an example. Now, could someone explain to me why Honolulu is in the second category while Newark is in the first? To me, they appear to have the exact same characteristics: three letters, in order, but not contiguous. Newark. Honolulu. What's the difference? CapnZapp ( talk) 18:40, 16 September 2016 (UTC)
A former name is not the same thing as an exonym - a name by which a place is known in one or more foreign languages, other than those of it's inhabitants. Some exonyms have fallen out of common use, to a greater extent than others have, but that still doesn't make it a "former name". Lathamibird ( talk) 07:07, 7 November 2016 (UTC)
A source said it could be given 17576 IATA possibles codes (26 * 26 * 26). It assumes there is only letters in _ and _ and _. Are we sure there is no figures possibles in these codes ? -- Bouzinac ( talk) 10:05, 21 March 2017 (UTC)
Would it be interesting to add something about single airports that have multiple codes? The only example I know of is EuroAirport Basel Mulhouse Freiburg (3 IATA codes: MLH, BSL, EAP) but I guess there are probably others. Sinkingpie ( talk) 21:47, 6 January 2018 (UTC)
I'm trying to avoid getting embroiled in an edit war. Regardless of the the ultimate call on how the page should look, I would appreciate if we could be a little less rude in edit summaries.
There seems to me to be no good reason to blank out the colloquial references section. @ 2600:1700:F56:FE10:C5EB:2475:7674:52D8's objection appears to be that these colloquial references are done everywhere, and not just in the United States. This is indeed true; it strikes me as an even stronger argument for keeping the section. The section does not say or even imply that this is a strictly US practice, especially now that I have edited the examples section so it no longer says the American ones are "most common", and I have cited those examples (If someone would like to cite an example from outside the US I would welcome that; I couldn't find anything readily).
