So I was thinking about the upcoming AA/US merger, and the Boeing customer codes that will effectively sit with the merged carrier, and it got me thinking of just how many have disappeared over the years through mergers/takeovers. This isn't a definitive list, and by no means have I included all airlines, but I'd be interested for people to add to the airlines and maybe pick up codes that I've missed in some of the mergers/takeovers.

For the European carriers I've put the owning group, so there are multiple carriers in bold as they are still operational (e.g. BA and IB within IAG).

Quoting FlyCaledonian (Thread starter): * B7 Allegheny Airlines / US Airways * G7 America West Airlines

No Boeing deliveries at US Airways since the America West-US Airways merger, but it would have been interesting to see which customer code was used.

I wonder if Swiss's 777s will be called 777-358ER....

Quoting LH707330 (Reply 2): I wonder if Swiss's 777s will be called 777-358ER....

I wouldn't bet on that, since their call sign is LX (former Crossair), and not SR (Swissair - Boeing customer code 57)...

LATAM Airlines:
* 16 LAN Airlines
* 2W TAM

TUI Group Airlines
* 04 Britannia Airways
* Hapag-Lloyd / K5 TUI Airlines (Now used for all aircraft odered by the TUI Group)
* T5 Orion Airlines
* 8A Air 2000 / First Choice
* 9H Lesiure International Airlines

Thomas Cook Group Airlines
If any future Boeing orders took place I wonder if the 1K or CQ code would be reused?
* 30 Condor (From time as a LH subsiduary)
* 1K Airtours International Airways
* CQ JMC Airlines

Air Berlin
* G5 LTU International
* 1S Deutsche BA / dba
* 6J Air Berlin

I must confess, I've never understood the rationale behind having specific customer codes. Personally, I'm glad Boeing is doing away with them on new frames.

You can add the following which were all 737-200 customers and eventually became part of AC predecessors:
* 42 Nordair (acquired by CP Air)
* 96 Quebecair (acquired by CP Air)
* A9 Transair (acquired by Pacific Western)
