It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Italian airport boarding is always funny. But to not be able to load my luggage with over 1 hour layover is ridiculous

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

They charged a fee for 1st bag checked. Others in same party were free.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

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. 🙂

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

They made me pay $40 to check a bag that was listed as free when I bought my ticket. Then before boarding they offered to check any bags free.

Boarding was organized and timely. Food was mediocre, especially for first class travel.

RIC Staff was not enough. Elderly passengers had to wait 30 minutes to deplane, so we could board and still had to walk as no chairs were provided. And, passenger in front of my seat assignment rammed seat against my legs entire flight time. Was mildly bruised and left thigh still sore.

flight was good until we arrived at cmh ten minutes early but then sat on tarmac for twenty minutes because a plane was at our gate, so we had to wait despite the pilot tellling us that 3 other gates were open.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Did not get any refreshments. Crew was very nice but limited. Small seats

The only thing to like was that we eventually got to our destination

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

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.
