Dear T7PF
No-one else has offered an opinion in >24 hrs (which is unusual for prune) and given that we know little about you other than your nationality and your desire to pursue a career in aviation, so as a long retired military and civvy pilot and committed cynic, I would suggest the following:
1. It does not matter what age, or whatever or wherever you are - the realistic answer to your perfectly reasonable questions would currently be - You should assume the worst or most negative answers to every single question.
2. Even the most senior Captain in most well known world airlines would have trouble accessing most of the 'beneficial arrangements' you ask about.
3. In most airlines around the world, if you are at the bottom of the list - you do what your employer tells you - or you leave.
4. If you aspire to a career in civil aviation, you might do better by reading up on the Wannabes section.
5. I kid you not - whatever you might read or think - if you want to be a real airline pilot - It ain't easy. It's jolly hard work. It's family disruptive. Your management will squeeze you regardless of how loud you squeak. Your union will have little influence on your resulting miserable junior life.
6. Have you tried any flying, other than on holiday ? Or passed a civvy aviation medical ? What about a PPL for starters ?
7. I'm told the Indian Air Force is always looking for a few good folks.
Kind regards, LFH
