food /beverage service was limited to one time which was unexpected for a flight that long. food wasn't very good.

From the boarding crew to the FAs was such a good team. All with smiles and positive energy. The pilots made an announcement of us waiting on some passengers who were late landing and I didn’t hear one person feel like it was an inconvenience which was wonderful. Massive kudos to all that worked that flight. Everyone was united. 😊💙

Smooth flight, easy boarding process. Made up time in the air with initial delay due to weather pass through

awesome team work seen since on board till off plane in my destination. thanks you so much.

They did not have free WIFI and I was not okay with that!

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

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

It was serviceable, nothing special but nothing awful on this leg.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.
