How is Jetairfly a competitor? I really don't see how a charter airline for parent Tui competes with a regional scheduled airline at Antwerp?
I personally think that there are other niche routes available from somewhere like Luton.
bmi have done well linking in to Lufthansa as an example with through ticketing. Maybe this is the kind of market that opens possibilities for VLM longer-term espacially as the Fokker 50 fleet will have to be replaced with a new type at some point in the future?
