DL or B6 for PBI-JFK and back?

[AA 1818]

So I am heading to NYC for the weekend right before Christmas and was looking at fares. Both DL and B6 have the same fare. What do you guys think? Should I choose B6 b/c of the better ammenities? I haven't been on DL for a while. Anyway, and advise would be greatly appreciated...

Delta's 757 are pretty nice if they use them on the route. However if it's those damn MD-88's, i'd go for the A320 hands down.

Not sure when you are planning to travel, but for JFK we mostly use regular MD-88's but we do have some Shuttle configured 88's and 757's rotated in on different days all based on passenger volume...
I have never flown Jetblue so I cant give any advice on their amenities, but as much as I hate to say it they do still have the TV's on their flights which is a big selling point...
If you decide to fly Delta, which I hope you do, stop by and say hello...

Well, if you are a Sky Miles member, the answer should be clear ;) .
Other than that, it's amenity-free MadDogs vs amenity-laden A320s. Of course, if you haven't flown one of those 2 plane types yet, it would also allow to add a new plane to your repertoire ;) .
