I would like to ask your opinions: should I book early or wait? I'd like to try Jet Blue, but don't know if I should wait until Jan or Feb.
Last two trips we have flown USAir, one trip was a nightmare, flight canceled, lost luggage, my two kids sleeping on the floor at midnight in Charlotte

. It was cramped and hot not a good experience.
I'd appreciate any suggestions. We are flying out of Pittsburgh, July 21 thru July 30. Thanks
