The A300s are staying for now, while they are profitable. However there was some belt-tightening on the fleet a few months ago with a few redundancies.
Do you mean they weren't offered the 737? Why sack proven crew, and recruit for J2 at the same time
He is clearly puting all his eggs in the Jet 2 basket - a very questionable strategy
Not really, as many new 73s are freighters.
Good luck to my ex colleagues on the F27. Surely Trubs could do better than sell off his loyal workers?
