Not surprised at Jetblue. I've had a few delays with them.
Agree with jsphfcll, delays are annoying, but I'd rather the airlines delay than take unnecessary risks. The worst airports for me are JFK, EWR (srsly, fuck Newark), and ORD.
Back in Feb I was supposed to go RDU->EWR->FRA, and my outbound flight was delayed like 3 hours due to weather at EWR. They finally said we're boarding, and we get on the plane then 5 minutes later they said the flight has been totally cancelled. LOL. Thank baby jeebus I have status with Lufthansa, so I was able to re-route before the gate counter even opened to rebook all the peasants.
