LOL..
I didn't read your whole post but I also know very Senior Capt.s, FO's and SO's in the Airline. Some of what you have said is true but some not so. EG. 'you get put into a 3 star hotel', well the CX crew at where Iam stay in the Hilton or Hyatt hows are they 3 star?
End of the day if you are doing it for the money and a good lifestyle as I sense from your minor summary. Go into development or trading and not flying. Then with the money you make you can travel the world and be a frequent flyer.
As I said I agree with some of your points but not all and deff have another answer for the points I dont agree with.
Good luck on your future endeavours.
