Jetheat, the lifestyle is such that you will certainly see your fair share of the Golden Tulip Hotel in AMS. Typically you will do 4-5 nights away, then 3-4 nights at home (5 on 2 off, or 6 on 3 off). You tend to start on day 1 at about 0930 and finish in the UK at about lunchtime. This can always change.
Training is good. F50 done in Maastricht. Groundschool is Mon-Fri and you will most likely go home at the weekends. Sim takes about 2 weeks and again you will go home somewhere in the middle.
Expect to do a lot of sitting about in hotels or positioning. We seem to do many duty hours and only about 400hrs flying per year.
It is not a happy company at the moment. Route network is limited (ie. to and from AMS). Many lifestyle issues outstanding and pay is seriously falling behind the competitors. However, the guys you work with are great. It is a company which lets you get on with the flying without too much hassle and F/O's get a lot of responsibility. Shame it is not still Air UK. THAT was a good company to work for. KLM have screwed it up.
