so the plus class, is the old Thomson "extra" and TUI Airlines Nederlands (Arkefly) hasn't re-config'd the cabin of "YI" when it moved from TOM to TAN?
It's no longer known as Thomson Plus (longhaul economy). It's just either Thomson longhaul economy or Thomson longhaul Premium. It changed obviously during the merger with First Choice Airways where they had Star Class (longhaul economy) and Star Class Premier.
Wasn't Thomson extra from the Britannia days where you were offered extra legroom seats and a travel pack???
As for 'YI', when it left TOM it was configured with the new TOM longhaul since but no other configuration changes... As for what they have done to it since it left I don't know but seeing as though they have a 3-class product on their longhaul routes, I guess they will have added their ''Star Class'' Yes that's what it's called
