They canceled my flight going back to SF after I was at the airport. Wanted me to take a flight 14 hours later. Not a happy camper.

They canceled my flight going back to SF after I was at the airport. Wanted me to take a flight 14 hours later. Not a happy camper.

I didn’t like not knowing my seat till I got to the airport - and my boarding group was F (last).

Wasn’t an Alaska plane so the seats were very thinly padded- glad I wasn’t going further.

Clean plane, relatively spacious in Main Cabin. One experience: I'm 79, with torn rotator cuff (R shoulder). I asked for help getting my carryon into the overhead bin and was told that the staff "does not help with this" (or some such phrase. On previous flights, help has been offered (and accepted). I prevailed on a fellow passenger for this. Also, why not board back to front?? Would this not help in the speed of boarding?

Flight was late but crew was very efficient and friendly.

Flight cancelled an hour before takeoff due to "unscheduled maintenance". New flight makes me have to wait for 5 hours in the airport, at a gate totally on the other side of where I'm at, requiring me to take a tram to get from the N terminal, to the C terminal. After waiting for 5 hours I'm informed my new flight is no longer at the gate I'm at, but instead is back in the N terminal where I was previously.

No tv, movies for a 6 hour flight! Worst airline I have ever travelled!

It was great; it was on time, everything went smoothly, the crew was excellent. It was just uncomfortable for the usual reasons; completely full fight, could barely move because the space was so small. The expected stuff with every airline.

Ground crew was great in Austin, flight crew left a lot to be desired. Not particularly friendly, helpful or nice.

My baggage was in another flight, anit was delayed for one hour.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.
