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

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

horrible website for checking in- no option just to write the passport number; ludicrous

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?!?

Nothing, whole flight was a nightmare, was forced to check my carryon bag at the gate, staff was rude and unprofessional

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
