I aggree with bmibaby.com this was one of my points First Choice have been heavily pushing there new long haul service but to sell someone a 'Star Class' product only to give them something totally different is shamefull on them. Considering they have known this was happening
I think they should have atleast outsourced the flights to another carrier with suitable aircraft and seating,or, of all the aircraft lying around in this world with nothing to do there is one somewhere they could have leased/subcharted for a couple of weeks till they have their own suitable aircraft.
Granted I dont know the loads but how can you fit a 763's load into a 752 ?
