Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Coach seating is debilitating, neither my husband or I can walk the following day

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

We arrived early and finally made it to our gate almost an hour after.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

David went above and beyond to make our flight the best that it could be

Was a pain having to leave the plane and reboard but glad the plane was fixed

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

The bag drop personal were not helpful. There was no food on the flight. Boeing aircraft, lousy as always. Everything else was fine.

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.
