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.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.
