I was 23 years on the Mad Dog. When it left I had full intent to go to the 320. One good look at the rotations and I said no way. Lack of commutability, short layovers and a lot of block.
Senior on the 717 isn’t a bad place to be. Lot of long layovers, easy days, short legs.
I stopped seeking glamour and exotic locales a long time ago, and I’d rather get a good nights sleep.
