Traditional charter flights to Med. resorts are a declining business at virtually every UK airport, as far as I can tell, due to competition from low-cost airlines and people preferring to organise their own holidays, rather than buying a package.
I would have thought LBA has done rather well in terms of flights since the growth of Jet2 from nothing to the present scale of operations, in such a short time.
Pity about the displaced threshold to Rwy32 and the transport links though. Methinks these are priorities to be sorted if the airport is to realise its true potential, which is surely with scheduled flights, not charters.
