The Brits are always complaining about getting charged too much when compared to most other countries! Well here is one where we don't. But we still complain, theres a suprise.
I work for a large UK carrier operating the European destinations offering all the so called "frills". We are delayed to some extent by atc slots on most flight these day it would seem, so I don't think you can put it down to the price of the ticket really!
As for complaining about lack of food or selection of drinks(on a one hour flight), well I will bring my own bottle of water and a sandwich, if it means I am saving a few hundred pounds!!! That would by a slap up meal at your destination. But if you think the so called FRILL catering is worth a couple of hundred, more fool you.
