With "error" fares, is there a (reasonable) time limit for the seller to rescind the offer before it is NO LONGER considered an "error"?
[Several years ago AA was selling JFK-SFO-JFK Y for $135--I, and I'm sure many other FTer's bought and flew on this fare...AA never cried "foul"; plus their JFK-LAX-JFK for $200, got me a
free Y ticket anywhere (in the world) AA flew. In retrospect, all of this seems like a (wonderful for me) "error"
