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.

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.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

This is related to my second leg of the flight, from Washington DC to SFO. I understand things happen, but I got home at 3 am for a 12:59 am landing. I live 10 min from the airport. Bridge breaks when a few rows of the plane are off? Maintenance didn’t catch that?

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

great starting with the business Class that's was Amazing . thank you United Airlines and brussels Airlines

Best flight in years. Pre-boarding because of my mobility issues. Good food and beverage from beginning to end. Excellent choice of films. Good service by stewardesses. Comfortable seats. I could lie down!

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Bad check in experience. Dirty ancient aircraft. Truly awful food and this in Business/ First class.
