That is what i was wondering, the EXT charters are nearly always full according to my source, and FCA could prob base a 757 there all year round and operate full flights everyday. If EXT can fill a A310 to YYZ (altho it is split with BHX it still carries 100+ pax per week) surely EXT could have some more longer haul services, to stop south-west pax going to LGW/LHR/BHX?
FCA if your reading this then get some a/c based at EXT!!!
