one (more) caveat of using priceline...
flying out of jfk last night, i chatted with a student trying to get to chicago. her nonstop jfk-ord twa flight was cancelled, and no other airline would honor the priceline-issued ticket. she eventually got on a very late jfk-stl-ord twa flight which was delayed on the tarmac for an hour due to weather in stl (i know because i was on the jfk-stl leg), and missed a reunion -- a problem which may not have happened had she had a published fare.
