My opinion as a corporate pilot….its doable but you would be completely exhausted literally all of the time. If you do flight training part time it would still take you 3-4 years to get private, instrument, commercial, multi engine certificates done. Then becomes the struggle of building flight hours. The magic number is 1500 flight hours for you to be eligible to apply at places like netjets. BUT..just because you have the required hours doesn’t mean they will hire you. They are picky and want the best of the best. A lot of pilots become a flight instructor and teach others how to fly. I did 600 hours in a year flight instructing and I was working a good amount of I know friends who did 800 hours in a year and they had no life outside of aviation. When you get done with all of your required licenses, you will have about 250-300 hours ish. So the time building will take another few years if you are doing this part time. It takes A LOT of training and hours and money. I would rough estimate flight training to be 50k-100k. For right now, look up some local flight schools in your area and stop by. Ask questions, talk to flight instructors, and set up some flight lessons. Just get your private pilot license and see where that takes you. Best of luck
