I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

Horrible! I paid for a straight flight from Chicago to London. A week before trip it changed and now I had a connecting flight. Our flight was delayed an hour and a half because our flight crew was still flying in from CA. Forty passengers ran from one plane to the next. The next United Airlines flight was delayed two to three hours because of mechanical difficulties. They had to ready another plane which took time. I missed my scheduled excursion in London. 😢
