I flew JetBlue from Charleston to JFK recently. I was expecting an average or below average product from them because I’ve always thought they were a “budget airline”, but I was pleasantly surprised with my experience. Not only did the seats have way more legroom than any other economy class seat on any airline I’ve flown, they served full sized complimentary snacks! Not the tiny pretzel or peanut packs I’m used to receiving on Delta, but full sized snacks, which you choose from their basket. The snack basket you select from is very similar to the snack baskets on a regional Delta flight in Business Class.
I’m really looking forward to flying with JetBlue again sometime, hopefully in the near future.

In case you need even MORE legroom. But really, unless you’re 7ft tall, I think you’ll be plenty comfortable.
