Air Europe, possibly still 757’s and 737-800s.
Caledonian, well even if they didn’t join JMC (Thomas Cook) they would of retired their L1011’s and DC10’s and i predict they would of had A330’s as replacements.
Dan Air, Im going for a prediction of 737-800s.
Orian Airways, Still operating 737-300’s however an addition of 737-800s too.

Some other airlines to mention too.

Laker Air, Im guessing they would have A330’s.
Leisure International, Still having 767-300s they would of also had 737-700s.
