"well, the dash8s are pretty vintage themselves, but the point being made was bigger and/or newer planes. I'm sure the Jazz guys won't be complaining (at first) about the age of the '57s"
True but some of those Dash 8's have been recently parked. This 757 and other similar aged Boeings will be sent over with complimentary UK deferals and defects for the Jazz gang to deal with each winter season.
Enjoy.
