I think you cannot generalise it. I guess it all depends on which company you are working for, which kind of operation etc. I started my career with the airlines and now am employed by a major european bizjet operator. Didnīt find it too difficult to adjust and the general working conditions quite good, but I also understand that my company also provides a lot of support compared to smaller operators. My bottom line is: If you arenīt lazy, you shouldnīt have problems to adjust.
