Zap....there are many great pilots in the 121, 135 and 91 world. But many differences between them all.
One must remember that "flying" the airplane 121 style won't cut it in the 91/135 world.
The corporate world won't tolerate the fly me like you stole me attitude. I type this as the AA capt who is taking the J loop at DFW just moved me from 14 B to the aisle.
