I was in a similar situation as you; same age when I got out, married, former 15U . Dunno where yr stationed at but I got out at Ft. hood TX. I went to school got my associate's and bachelors while getting the flying done. My goal is right seat somewhere flying for a living by 30. Im 28 now, wrapping up my CFI and working as a station agent at Colgan at KGRK. I have about 320 TT. As soon as finish my CFI I will be moving onto ME, CFII and MEI while instructing. I can tell you it hasnt been easy. Enjoy yr GI bill it paid for a majority of my stuff but not everything. I waited tables and did minor maintenance on school planes for extra cash. As for regional airlines, I wouldnt worry too much about that right now. Like everyone has stated, **** changes! Figure out where you are going to go to school at and where are you going to learn to fly. I dont think I could have come this far without my highly supportive wife encouraging me hope you have one too cause yr gonna need it. Alot of my friends that got out with me did contracting jobs making 100k/yr and its very hard to fight the temptation to do the same because you will never make that much flying for a long time to come. But I really want to do this, not for the money. Its my dream and until I am told I cant medically Im gonna keep on trucking along. If you have questions PM me. Good Luck!
