I fly PHL-LAX rt's fairly often. The last three years, during the weeks just after Thanksgiving and until about a week before Christmas, these rt's were offered for no more than $200 because of low loads at this time of the year. But this year there are no bargains, although loads look extremely low: no more than 50% in some cases.

So why doesn't US try to fill some at least some of these seats with cheap fares?
