LAX, The Name,from Where?

Mon Jul 13, 2015 4:27 pm

Now before you all jump on me this is a question from an eight year old, I could not answer.
He understood the LA part and then said, what does the X stand for?

Over to you people.

Some airports use to use 2 letters for their designation, such as PD, LA, PH, until the industry expanded and airport codes were standardized to three letters. So they added an X, hence PDX, LAX, PHX etc.

Actually not sure if PHX was one of those or not...

You're not the first to ask, it's even on their website.

What does the "X" in LAX stand for?

Every airport today has a unique three-letter identifier to streamline the process of tracking the millions of items of airport data transmitted daily, including flight plans and weather reports.

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.

I am guessing the Y at the beginning of Canadian airports has to do with this as well? That intrigues me even more.

Not all Canadian IATA airport codes begin with Y. A fair number begin with Z and some with Q. And not all ICAO codes can be converted to IATA codes by deleting the C. Some have an IATA code that's unrelated to the last 3 letters of the ICAO code.

Thanks for starting this thread, I've always wondered the same but haven't really searched for the reason.

I've always held LAX to be one of the most iconic airport codes, possibly second just after JFK.

I still like LAX the best FWIW

They can also add an X to the beginning of the code as well, in the case of XNA.

Then there are the 'international airports' from the 60s --

IAB -- McConnell AFB

IAD -- Washington Dulles

IAG -- Niagara Falls International

IAH -- Houston Intercontinental

   "X's" and "Q's" are used as "filler" for predominently 2-letter codes; thus LAX, LPQ (Luang Prabang), et al...

I think this has more to do with no codes starting with the letter "N" such as EWR for Newark and ORF for Norfolk.

"N" is reserved for naval installations. Notably, in 2008 Yuma's airport (which is a joint military/civilian airport, although primarily a Marine installation) changed the civilian FAA and ICAO designator from YUM/KYUM to match the base's NYL/KNYL (but still retains its IATA code of YUM).

Yeah, it's enough to make your head spin.

I don't think PHX worked out that way. The name Phoenix already has an X in it.

For me LHR is quite there on top, but then again people don´t say "I´m flying out of L-H-R", but rather Heath-row (I love how the British put a stress on the second syllable!).

SFO and MIA are also quite often used instead of San Francisco and Miami.

LHR"s code was LAP (for London Airport) until it was changed to LHR sometime in the mid-to-late 1960s.

Quite a few US airports have different FAA and IATA identifiers, more than you would first guess.

And on the subject, Chania is another example of the placeholder letter, in this case Q.



And to add another wrench to the works: why do most of the airports in the Aegean Islands start with J? e.g. JTR, JMK, JSI etc

I was told that "X" was an old term used to signify station, back from railroad days (X may be related to crossing?). So when they started converting two letter codes to three letter codes, they simply added an X. I have not been able to verify that, however.

I never new this about LAX. I thought the X was for international. Same as Jacksonville International. Neither of those airports have anyone's name associated with the airport, which is surprising especially for a city the size of LA. I realize TBIT does but that is just a terminal.

Yes, quite a few in several countries. Three others in the U.S. come to mind:

Quoting RyanairGuru (Reply 22):

"J" is a designator for(mostly)smaller airports worldwide generally for small turboprops or Helicopter airports. Long Beach, CA, for example, has---besides the regular airport---has a helicopter airport "JLB". And the Marriott hotel at Schaumberg, IL which is near ORD, has a heliport with the code JMB.

Santorini is JTR because the island has another name, Thira. Most of the Aegean island airports have some logical sense, whether it starts with "J" or not. The only one that doesn't really make sense is Karpathos, which is AOK.
