I was flying JetBlue back in August, on that day when the scare went up about the gel bombs, and things were delayed all up and down the East Coast. We were hurried onto our connecting flight at JFK, then had to sit and wait for two hours for the clearance for take off. If we hadn't gotten on the plane, though, we'd have had two hours to wait IN the terminal as well as on the plane because of the enormous back-up at the airport. At least we were able to watch our personal back of the seat TV's while waiting on the tarmac.
They'll never fly to CRP. Theoretically I could fly from CRP to HOU on Southwest and HOU to JFK on JetBlue, but it would have to be on two separate tickets. If flights got cancelled due to weather, it would be difficult to get reimbursed or rescheduled. I detest Southwest's no interline baggage policy. It locks customers from small markets like CRP into only flying connecting flights on Southwest. No airline is going to try to compete with Southwest on the CRP-HOU route, so it's not worthwhile to book flights with any of the airlines flying out of HOU except ATA, because of their code share between HOU and LGA and the cities in Texas served by Southwest.
