You need to have an idea of what your timeframe is. If you're planning to stay till retirement then well and good, but most people dont plan to stay long term when they first go to the desert. My experience is that most people have a 10 year timeframe in mind. If that is the case then there are a couple of things to consider.
Firstly, in 10 years you are extremely unlikely to have accumulated enough wealth to just walk away. If you have, then you a wasting your time as a pilot, you should be a Professional investor.
Therefore you need to consider what your escape plan is. After 10 years you are unlikely to find another carrier that you are in a position to join that offers anywhere near the conditions or security of EK. Accordingly, like many who came with a 10 year plan, you end up being a lifer. Not because you love it, but because you cant find an acceptable alternative.
Having said that there are many who do love it.
I've been gone 4 years and have an excellent job, but I'm still not sure i did the right thing by leaving
