The Hilton Hotel at Bournemouth is having a recruitment day on the 24 Aug which has been booked for a long time now ( friend works there in the conference suite and its the first time they have had an airline take up a day here )
It is more than likely a road show for cabin crew though and probably doesn't mean anything at all so no speculation as yet ( STN base ? )
Jet 2 go around the country each year doing this , I would love to be proved wrong though !!
