Well you asked, I told you what I think. You seem upset because you did not get the unicorns and rainbows answer you were looking for. You asked the advice of us who have or had a professional airline career and you got answers, mine obviously not living up to your Pan Am glory days idea of airline flying.
Im telling you now, having been there and done extensive flying not just in airlines it is a waste of time and there are a lot of better careers out there. Even within aviation I would do something else besides airline flying if I could go back and start again knowing what I know now.
For pure aviation satisfaction and to feel like you are achieving something worthwhile I suggest something like the RFDS or Life Flight Australia.
Believe it or not Im actually trying to save you a lot of pain and heartache. However at the end of the day the decision is yours and if you go for the airlines I wish you all the best in your future endeavors....
