perhaps people WILL pay for SOME, but not all of those seats.
But its never been this bad as far as I recall.
For me it would be a little easier to fly AA or UA BOS-SFO, nonstop. I have the miles to UG on AA too... its tempting, especially if I do a challenge.
There is the additional possibility that with the recent capacity reductions, their Yield management people haven't allocated F seats, I'm hoping that is the case. We'll see in the next few weeks.
