Think the " proper airline " comment was with tongue firmly planted in cheek! It's just too easy to take the pi*s out of the charter boys, their all nighters and long gangly 757's!
Just what do you consider a proper airline would be anyhows? And Girl Friday don't worry about the whole being tied in to an airline thing, you arn't you can go where you like after 6 months, you're just a normal employee like anyone else. It all comes down to weighing up your options wrt pay and conditions at other airlines.
