Not really. If Ryanair is half the cost of say Lufthansa for a 2 hour flight, I'll go with Ryanair. A flight is a flight, I'd rather spend the money on a better hotel or eating out rather than a marginally better short flight.

I've never once seen people fighting or screaming on a cheap flight.

For long haul I have no problem going with better airlines (which still means European or Asian over US carriers every time...).
