You quoted fares on a particular day, on a specific route.
Its impossible to say which carrier will be cheapest from day to day. Or who'll be cheaper on any given route. Yield management by online booking engines constantly adjusts fares. Shop around.
The 'average fares' quoted by the likes of O'Leary should be taken with a pinch of salt, just like everything else he says. He doesn't include all his extras. Its a meaningless figure.
Aer Lingus is now dumbing down to become FR Mk2.
I don't like where its going -but its too late to reason with the punters. They refused to see the writing on the wall when differentiation still existed...all you got was complaints about 'expensive legacy carriers' ripping them off.
Now they complain about nasty LoCo's ripping them off!
Zero sympathy. And it'll only get worse.
