Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

The business class service was very good. The crew was helpful and the food was enjoyable. Boarding was well organized.

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!

The flight crew was the worst I've experienced. If they worked for me, I would fire them immediately. They never smiled, they seemed angry and avoided passengers as much as possible. The food was not edible, and my luggage was lost. I will never fly United again!!!

Fought with Lufthansa was poor, seats are uncomfortable, food was bad and luggage did not arrive to IA

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.
