Speed alive:
To answer some of your questions.
Salary hasn't changed for many years except the increse of index from the Luxembourgish state. Per diem has technically increased (from USD to EUR).
After training you get about 4,200. As single you end up paying about 30% tax. About 800 tax free per diem is on top of that.
Roster still the same, 4 and 7 in every 28-days. 42 days vacation.
Average trip is about 7 days.
Hours flown is everywhere between 400 and 650 depending on seniority I would say. Some other guys would disagree. But it is a difference to always fly Shanghai and back or stay a week by the pool in Brasil.
Future outlook. Ah, now it gets interesting. Here probably some of my colleges will "correct" me. But whatever you hear the best answer is - nobody knows. The latest information in print is that in 2015 the company will have the same amount of aircraft as they have in one month (16). I fly more and more with guys saying they now expect between 15 and 20 years in right seat. Many have started to look for other jobs (not saying they will find something better). People, although small numbers, do resign for Air France and NetJets mainly.
Negotiations for a new CWA is coming soon. We all hope for some improvements, mainly regarding the rostering. Still one's private life is not always respected. For example they call you on your vacation or time off, they bring you home late (on off-days) etc etc. The whole operation is very tight. If something goes wrong (AOG, wx, overnight delay in LUX etc) the network (including the crew's rosters) is very easy distrubed.
