I think a lot of the pax are indeed new. TUI however, are up to their usual tricks of selling a flight from one airport and then transfering pax to a lesser selling flight from DSA. They are experts at it , it used to be sell from LBA and then cancel the flight and move the pax to a less than full flight from MAN. Now they're doing it fron DSA rather than MAN. Still 500,000 is very impressive and its isn't having too much effect on other airports in the area as pax figures are still on the rise at those airports too so fair play to Peel.
