P4GAS and P4FAS have both undergone major cabin refurbs with new leather business class seats. They don't seem to have done much with economy though, still, with an average load ex EGLL of 15 to 30 punters down the back, I would have thought that taking a few extra rows out would make all the difference. B757 crews are trained by BA, and are doing a fine job, the locals are doing very well. As for the props, I'm not sure who is training them, or if KLM/NLM have loaned crews to them for an extended period as is the case on the B757 fleet. I assume they want to retain high capacity in econommy due to their route plans to go to india later this year.
All in all a very nice airline, I'm sorry but what ever happened with the F50 didn't draw alot of attention, so I cannot help on that issue.
