There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

We arrived early and finally made it to our gate almost an hour after.

Overall great. I was forced to check my carry-on backpack from EWR to BOS but it came out on the luggage carousel so fast I didn't even get delayed for my pickup.

Flight attendant gave incorrect information and no immigration/customs forms!

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

There was no air on the plane and it was very hot.

The free snack options are pretty pitiful for a 2.40h flight.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.
