i've paid as little as $333 pp for a direct flight from phila and as much as $500 pp..this year direct flights from phila on us air were going for around $850 pp going last month..i got lucky and found a flight on delta with a 2 hr layover for $319 pp..this year for some reason the airline industry has gone a little crazy..you just have to be smart and keep checking your flights day in and day out..also, you can use a web site such as
www.kayak.com which finds you the cheapest flight on multiple carriers or
www.yapta.com which if your flight price goes down you will get a refund..some travel experts say that you usually get the cheapest price from the airlines own website because sites such as travelocity charge you fees..also, experts say that tuesday night between 12 am and 3 am wednesday morning is when you might come across the best deals because this is when the airlines put in their low prices after seeing how they did sales wise over the weekend..
