The high yield flights justified the existence of the lower yield flights. EasyJet ran an A319 up against them at the busiest times and capacity-dumped, meaning the whole route stopped being profitable.
Yes, that's competition, but the overall effect is a reduction in connectivity.
It's the same with the Liverpool flights. In summer and at TT you can't move for EasyJet planes here, but in the winter EasyJet don't even run a daily flight. The net effect is the Flybe flight, and now the Loganair flight, ends up being supported by the taxpayer.
Again yes, that's open skies competition, but it's not brilliant.
I wouldn't mind, but if you look beyond the headline fare EasyJet aren't even that bloomin' cheap. And IME EasyJet cabin crew make Ryanair crew look full of the joys of spring!
