Airline reviews

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Typically flights with AA are good. The staff are pleasant, welcoming, and efficient.

A couple ladies from the crew were so rude and nasty. Thought they were mad at having to be there especially if you asked a question. This will make me think twice next time if I book a flight with you.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

Flight attendants on this flight were very attentive and friendly

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.
