It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

l really enjoy very much the flight was very pleasant

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

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

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

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. 🙂

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

Efficient all round, very good crew. Short flight so the food, of course, was just snacks
