Sorry if this question has been asked before. Haven't found it on archives however. Could anyone tell me where the X in LAX comes from ?
thanks in advance

The "X" has to mean something? Probably just an extra letter added to meet the 3 letter code standard.

At LA Airport there is a odd looking building housing a restuarant and when you look from above it is an 'X'. So when you fly over LA looking for the airport you look for the X!
True!

I think the X stands just to fill the gap for a three letter code as LA alone wouldn't qualify.

The same thing the "F" in MAF does and the "J" in SJT........nothing. It's just an abbreviation and LAS was already taken.

No, it is this building that stands for the X.

I can hardly believe that, as I'd think LAX was already LAX before that building was built, however i'd be happy to be proven wrong  Smile

From Wikipedia:

"Before the 1930s, existing airports used a two-letter abbreviation based on the weather station at the airports. So, at that time, LA served as the designation for Los Angeles International Airport. But, with the rapid growth in the aviation industry, the designations expanded to three letters, and LA became LAX. The letter X does not otherwise have any specific meaning in this identifier."

Exactly right! The X has no meaning other than to complete the 3-letter code.

In the1930's and 40's LAX was known as "Mines Field". But I do agree the "X" has no meaning and is only used to create a three letter IATA code.

MAF was probably shoterened to the required 3 letter code from MAAF or Midland Army Air Field, the name of the field in the early 40's.

Like EWR is from nEWaRk or EYW is for kEY West, SJT could be as a result of San angelo, Jack maThis field.

The field was named after Lt. Jack Mathis.

Well AFAIK pretty much all continental US ICAO (not IACO...) codes are K+IATA code.

Almost.  Smile

Alaska is a part of the North America continent and also an U.S. state, but its ICAO prefix is 'P'. For instance, PANC for Anchorage.

I think you meant to say 'the continuous Lower 48 U.S. states' rather than 'continental U.S.'

I quickly learned the difference after visiting Alaska on various vacation trips, since the Alaskans didn't really like it if I made that particular goof.  Wink

Yeah that's it. Big grin

I always thought P stood for "pacific" or whatever.

OGG seems to also have a different one, PHOG.

The ICAO codes often make some sense in Europe like EFHK (HEL - Europe Finland HelsinKi) or so.

Here is the correct answer. The "X" was added after air transportation started to catch on the existing airports such as Los Angeles ( LAX ), Chicago Meigs    ( CGX ), Portland ( PDX ). Brought those places, and others, into compliance with the three letter airport codes. Just simpler to add an "X" and press on.

In the ICAO system, P is used for the first letter of US airports which are on or in the Pacific Ocean. The second letter is a modifier, PA is the first 2 letters for Alaskan airports, PH is the first 2 letters for Hawaiian airports. There are other combinations used for US territories or US affiliated airports in Micronesia and Marshall islands: PG, PK, and PT.

Thanks for that DxBrian, PANC and PHNL didn't exactly make it clear for me. I thought K for lower 48 and P for the rest.

I don't think LAX is any of those. Maybe poor design, but they are working on that.

T1 might be a bit crowded too I guess, but I all in all, I like LAX.
