“How many people want to spend a weekend in Paris in January? And how many of them will pay a premium to do it?”

Key point, how many are willing to pay that premium. Perhaps AC should consider some more reasonable fares.

If the planes flying, surely get almost anything for the seat beats nothing. I mean how much does it actually cost AC in fuel, food etc ... to fly and feed a standard human with 20lb + 20lb luggage x miles?
