Have to say I worked as a F/O with Luxair in the early 90's. on the 737s. Some of their Capts were basically appalling but I liked it their. Engineering were top class and the 737 's were minded like babies.
If I didnt have a ball and chain with kids attaached else where on this planet I would move back to Lux in the morning. They are an odd race, a bordering on hate or love of germans, french and the dutch. Std of living there is tops and salaries v good.
If I was starting off again Lux would be very desirable. I'm sure Luxair have come on leaps and bounds since I have been there so go for it. They'll make a mule of getting into the co. but all these assessment interviews but once your in your in. When I was there fuel was never an issue...maybe same today.
Best enginneers I have ever dealt with....and I have dealt with a lot in my day.
