that has happened, but the two that did the "advanced program" came from the operations department.... so were basically managment "friendly" people. although id say that they arent complete backstabber management lovers;
the chances that advanced cadets get in are small as previously stated, in theory you would owe them less, but in reality they would push on you a contract that would be just as overweight with company advantages that it would be unreasonable.
I would just go the G.A route. I am not sure why people want the "shortcut" so bad, especially if your in your 20's. get out and see what its like and appreciate the industry for what it really is! believe me, its not all its cracked up to be to be a Rex cadet! ....
Better off going to Q.link if your an advanced cadet/cpl holder. All I can say is go G.A.
good luck
