They are both reliable. That is only about a 2 1/2 hour (or so) flight, so don't sweat the small stuff. Just go by convenience and price. Chuck.
I would choose Jet Blue over Delta.
I prefer Jet Blue over Delta, even for short flights. That assumes that there isn't a massive cost difference.
Jet Blue > Delta........but it also depends on cost.
Thanks all. As prices are much the same we will probably go with Jetblue.
New York had multiple airports. Are they both flying from the same one? That would be the other consideration.
JetBlue flies nonstop from JFK to New Orleans only.
