Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

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

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

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

As great a red-eye flight as red-eye flights can be.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

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