Terrible experience! delay 2 time and say i dont have ticket

It was amazing. I had several upgraded seats on my flight out. Everything went smooth with no delays.

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

Flight attendants had a little attitude. Food tastes no good.

Overall we had a good experience during our flight from San Francisco to Houston.

it was a very short flight so my expectations were low.

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.
