You can also go online and change your flight to eariler time/date if you still really want to go to Philly. Depending how far in advance that trip is the same fare could be available, even if it's this weekend, upgrade to full Y is likely not that much on a short run like that. ($102 - Fun Fare = Upgrade) No change fees.
