We have JetBlue flights for marathon weekend in Jan (10-14) and went in today to check times for rental car pickup and dropoff. JetBlue changed our flights by over 2 hours each way. The times still work for us but we were never notified of the change. When we called JetBlue to make sure which flights they changed us to they said they made major changes to their flights times. I know they also changed my sister's flights in Dec. Just wanted to pass the info on - I will now keep checking to make sure there are no other changes along the way. This is the first time we have had this happen with JetBlue.
