I hadn't flown JetBlue in a while, having switched to Virgin America several years ago. VA bizarrely doesn't fly between new York and Chicago, so I was forced to head back to JetBlue. It's fine, and the staff is nice, helpful, diligent, and really care about doing a good job, so that's the good. They went out of their way to make sure the flight left on time, and we got in on time. On the return flight the flight attendant seemed a bit less on top of things, but still tried.
That said, things just went less smoothly than I've grown accustomed to. I was also unpleasantly surprised by the other patrons. My screen wouldn't work on the flight out, so I waited until the flight attendants came around and asked them to reset it, but I guess it was actually broken, so they eventually had to move me. There were a bunch of open seats, all middles obvi, and I swear I felt like Forrest Gump--literally no one would let me in or take their junk off the seat, like they were entitled to an extra seat. So the clientele basically sucked, and the flight attendant seemed to know there was an issue with the screen, but hadn't proactively moved me before people got too attached to their extra seat to let me in. I mean people were literally ignoring me and the flight attendant, like they all couldn't hear or see us, or didn't speak English. The flight attendant really wanted to help and cared about people's flight experience, but wasn't quite assertive enough to help me.
Back to the flight, there were delays somewhere so they used a VA gate to get us out on time, which was cool. We left and arrived on time. The attentiveness with drinks and free snacks is nice and seemed standard on JB. The bags came out very quickly at JFK. In Chicago security was a hottt mess, barely moving for no discernible reason; I'd had such high hopes after there was no line to get my ID checked, then we just stood at security, with the scanner not moving for a while even though there were TSA people sitting there and generally standing around.
Long story short, it's not VA, but it's better than just about everything else, and I'd fly it again, but try to get on the screen issue or others sooner and more proactively. Also, they did end up giving me a $15 credit for a future flight because of the screen issue when I called and asked for it, so their customer service is decent.
