Flybe
That would be an interesting decision and the figures tell an interesting story but of course without yield.
Flybe flew only 2000 less passengers to LPL as MAN in July - 8000 LPL and 10,000 MAN. LPL up +20% and MAN down -1.5%.
Here is what the airport said:-
The Liverpool route, with Flybe and easyJet operating up to 6 flights a day, led the way with a 20% increase in traffic, generating 2,560 more passengers than in July 2010. With only slight decreases on the Manchester and Blackpool routes, north-west traffic in total was up by almost 2140 passengers
