If I were you, I would keep my FA job and get your ratings on the side. I know a couple people who have done that and it has worked out very well because they had flexible schedules that allowed them to devote some time to flight training, but they were still making money and getting benefits, etc. Then I might work on getting an online degree at some point, maybe while you are flight instructing or flying for a regional. But keep that FA job for as long as you possibly can! And use your job to network as much as you possibly can!!

Also, there really isn't a difference between male and female pilots. It is true that more and more women are getting into flying, but the numbers are still very low. You will always be way outnumbered by the men. Embrace it.
