Have been looking on the US website for next month's travel and find that virtually all of the flights CLT-PHL, CLT-DCA, CLT-MYR and returns show F sold out on most of the 8 dates I have searched. Granted there are some available but they are few and far between 2-6 weeks out. Have not encountered this in the past year. If they are truly selling these F seats, it makes no sense to be pulling them out of the 320's. Anyone else encounter this phenomenon? As a CP, it means zero chance of an U/G and one less reason to stay with US.
