Business class seats felt very cramped compared to other airlines.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Both my flight where delayed Had 25min to make it to my transfer flight

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.
