At KLM don't look at the short perspective, but at the long perspective. You will start with a wage between €70.000 and €100.000, but after 25 years (as captain long-haul), you will go over €420.000, excluding per diems (really good, for 24 hours CPH it is €150 NET or for a 4 day HKG it is close to €900 NET) and bonuses (at 100% contract). Their pension is great - by far the best in European aviation, all kinds of part-time possibilities, maternity leave, sick leave, ... (You will earn the same when flying 0 hours or 900 hours, the only difference are the per diems). After 1 year you can commute for free between your home country and the Netherlands and many more items (do not even start about asking questions like food when flying etc.)
