I guess you are writing regarding the few ex Swissair crew members. For the rest nothing against Thais, they are lovely, but 50 % of the crews are Thai nationals on the BKK route and this is certainly not Swissness. Guess they are paid less.

LX is only about greedy overpaid management as almost everywhere in Switzerland where you have to be part of a "clique" - it is called "Vetterliwirtschaft" and very very Swiss.

The only airline within the LH group that keeps some of its character is OS. They are very Austrian indeed, including the crew. You have to like red colour tough .
