They do already. I once got a $260 AI round trip from Newark, NJ, USA to Cologne, Germany. There were only a few seats per flight available at that price and I got it at 3am.
It was part of their usual shady promotions where they say "flights from $199" and there are really only a couple of seats available at that price, and they go fast.
