They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

We boarded late. The crew at the airport was dismissive. The seat cushion on the plane was uncomfortable.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Door to door, the crew and staff were amazing. It was a stressful travel day with delays, but they were focused on customers and doing what they could to get us to our destinations.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

United has come a long way, it’s been a fantastic experience traveling with them.

My flight was delayed about three hours. I got home at 3:30 in the morning very bad experience.

I like that the crew kept us informed but we moved back and forth from gate to gate before the aircraft arrived.

I like how the crew and pilot kept us updated Even though our flight was slightly delayed. We made up time for it in the air. I really did enjoy my seat and amenities and my trip and value overall.

The flight was delayed multiple times, again no fault of American but again the extra cost, for everything makes it feel like a cheap airline! Especially when flights are outrageously expensive already

The inflight staff is never the issue always the extra and charges american charges! Literally 30 bucks for WiFi! Is insane and then it’s choppy and slow. If you pay for it once you don’t need to pay again for switching aircraft especially when there is flight delays

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

I had a positive experience on American. I'm blind and traveling with a guide dog and the flight attendants were so kind, friendly, and helpful towards us. They checked in on us during the flight and they made us feel comfortable and welcomed. There was an hour delay before depature, but overall the flight was a smooth ride. I appreciate that there were no issues on this long flight back home.

We were told the flight was delayed 5 times, then it was moved to the next day.

More choices on snacks. Built-in video screen to enjoy entertainment choices.

we landed at cmh ten minutes early but had to sit on tarmac for twenty minutes because a plane was at our gate despite the fact that 3 other gates were open.
