MDRT22 as a long time pilot in the airline world, now retired, my advice would be to stick to the banking profession/industry now. If you have potential, get into M&A and with a combination of very hard work and 18 hour days for a year or two, you might just get to be able to buy your own airline. You'll most probably trade an airline, which can be a lot of fun too.
Then you can buy a decent aircraft for fun, and get a Netjets contract for the rest of the time.
I'm relating this story because a school friend of mine did exactly as above and he is on a vastly higher economic level than I am now. It is possible outside of the airline world to do the above, but it is not possible if you join an airline as a junior pilot and work up.
