so all of a sudden F availability to US west coast over Christmas 2011 is wide open - but only happened after the rise in YQ as I checked right up to the increase.
At 355 days out there was virtually nothing, so those of use who booked the virtually nothing now have to pay the increase in the YQ to change the flights.
Oh well, at least I have the dates I want now. If anyone is looking, seats every day virtually to LAS/LAX/SFO/PHX in F as long as you come back before New Year.
