In the meantime, DL are bleeding more money a day than I'll probably come across in a lifetime. They are a sole Boeing operator, is that a coincidence?
UA are also posting unbeliveable losses, and they are a mixed Boeing / Airbus operator. Is that a coincidence? Same with Air Canada, AA and UA so it's gotta be that then. Hang on, just remembered that Emirates turned in a very nice profit, and they operate a mixed fleet of Airbus and Boeings. Same with Air France and Lufthansa.
SAS bought a fleet of 50ish 737NGs, + a few 321s and 330/340s for longhaul, while retaining a few old 767s, quite a few MD80s and 90s, a regional fleet of Q400s + a few old F50s. They are loosing shyteloads of dosh. Shall we blame Fokker, Bombardier, Boeing, MDC or Airbus?
Singapore used to turn hefty profits, but did experience a loss in 2001/2(?). Ahh yes, that was the year Boeing sold them 777s to replace their A340-300. Is that a coincidence?
You forgot about JetBlue ......
