Well, you may be surprised that the rate of people leaving is far smaller than we often hear about. Just like all the pilots that are leaving..... not!
For a Company as big as EK, with a known short to medium term job as cabin crew, the resignation rate is well within what's planned.
To me it makes perfect sense for a young single person to do the job for a few years, especially given their likely disposable income. Whether you'd want to make a long term career of it is a different matter altogether.
