Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

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

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!
