I would recommend staying away from loans altogether if all possible. I have heard some shady operations on the key bank side of things regarding how they handled the entire ATA fiasco. Its best to stay debt free and pay as you go then you dont have a huge loan to pay off when your done with your training while your only making probationary F/O pay... The intrest is also racking up the entire time you are flying regardless of who you go with. Just best to stay debt free then the money that would go to the loan payment can go to food to fill up your stomach
just my .02 though. I think they both have their ups and downs
