If you need to ask, are you sure it's for you? Something has to get you up at 0330am. It won't be the time off you're getting, it won't be the money. The only thing that will do it for 35 years is the love of the job! You will probably have less time at home than office wallahs, certainly less time at family times. You will miss Christmases, Easters, Bank Holidays don't exist. Several times a year your job will be on the line with medical checks, 2 hard simulator checks a year, route checks. Stress wise, you will get aggravation from delays, ATC slots, ground staff, tension inflight, weather and technical problems. If you are not committed now, don't proceed any further. Hopefully something is telling you this is what you want to do!
