I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Having to up charge for a seat assignment is not good. Delta can do better

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

They did not have free WIFI and I was not okay with that!

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

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.

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

Very Poor. Significant delays getting to Chicago and then very poor communication on delays in Chicago to Cleveland. We could have rented a car and driven there faster than the delays ended up being.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

Late boarding by three hours. No Wi-Fi. No screens. Cramped seats. Sitting on the tarmac for 30 minutes after landing waiting for a gate. Delay in luggage getting to baggage claim.
