However, don't take the list as iron clad. This is not a page/ section editable by just anyone. But obtaining updates from IATA and ICAO takes time.
You can sort the table on any of the column headings.
As to why airlines might change their code
1) IATA uses 'controlled duplicates' where two smallish airlines in widely separated parts of the world have the same IATA code. If one of the airlines grows to a wider service area - one will have to change their code.
2) IATA allows any delisted code to be reused after 6 months. A desired code by an airline might not be available when the airline is started, but when it becomes available - the airline takes the new code and changes.
The assignment of code letters is based upon the preference of the airline if the code is available.

There are many times more airlines in the world than IATA codes, many of them are regionally used different airlines. Having to decode them for an AI project, I have no understanding why anybody still uses this crappy system, which only works in the US and is abandonned by 90% of the world.

Isn't there a German airline called Hahn Air whose business is to let a shipload of other airlines use their IATA code? And to be a legit airline they fly a bizjet scheduled between LUX and DUS like once a day? I'd have to read up on this. This is why you book some obscure route in Africa and the airline comes up as Hahn Air.

Quoting photoshooter (Reply 3): Perhaps when there's a name change yes, but Eurowings didn't change their name when they changed from NS to EW.
Quoting rfields5421 (Reply 9): 2) IATA allows any delisted code to be reused after 6 months. A desired code by an airline might not be available when the airline is started, but when it becomes available - the airline takes the new code and changes.
Quoting Putnik (Reply 10): t seems that Swissairs old code SR is still not being reused. Does anyone know why?
The liquidation of Swissair's assets hasn't yet been completed. I expect they don't want to recycle the SR code until Swissair is officially dead and buried.
Quoting Putnik (Reply 10): How did they manage to keep it dormant for so long? It is owned by Swiss?
Airlines don't own their codes. They have rights to their name, which LX purchased fom the Swissair liquidator a few years ago for something like $10 million, not because LX had any plans to reuse the Swissair name but because they didn't want anyone else to be able to use it.

What do you mean? Airlines can't distribute their product through the industry GDS systems unless they have an IATA code. If you are implying that airlines from 90% of the world do not have an IATA code you are very wrong.
If you're referring to very small airlines that don't interline and don't care about distributing their schedules through the industry systems, they can of course exist without an IATA code since they only need an ICAO code for operational purposes.
