How are the pilots who have bought the right seat going to move up into the left seat with no PIC on type? If seniority doesn't get you there any more, either because the companies don't last long enough, or they only hire DEC's with 500 PIC (which they must have got at another carrier or "parker penned"), how do you get your first common jet type command. It seems inevitable that airlines will start to sell this experience so that people can get over this unfortunate "catch 22" situation.
