⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Great, except the canon was so cold. Even the flight attendants put jackets on

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.
