Should I be worried?

[Prism]

I don't know about PA but here the prices go low then high then low again. I bought our tickets for Feb 8 at the beginning of Nov when they were low. They went high a couple of weeks later and stayed that way until the beginning of this week when they went low again. It seems to be the norm that a good time is 3 months out then again good prices 4-6 weeks before when they lower the fares for dates that still have a lot of availability. It helps if you have a bit of leeway with your dates. Also use this site to keep an eye on rates. I always use the calendar of lowest fares option
