Obviously reinstating a Birmingham flight is the next big target for LDY but I note that LDY flew 50K more passengers to Liverpool last year than BHD did.
BHD doesn't have Bristol or Newcastle routes either.
LDY did formerly have 40K pax p.a. to BRS but has never had a route to Newcastle.
Both Newcastle and Bristol airports have more passengers than Liverpool airport.
However even if LDY got these three routes its passenger numbers would not exceed the peak of 2008 as it lacks the frequency on the routes that the other two airports have.
