Airline reviews

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

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 room where it was being kept.

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

Really good experience with a redeye flight from SFO to BWI. Boarding was efficient, plane was comfortable and newer than others, lots of audio and video choices, and staff was great. I appreciate United's service.

Textbook great flight. On-time departure and arrival, clean plane, good food, friendly flight attendants. Checked baggage delivered promptly.

Liked Seat space in Premium Plus Disliked delay, poor management of boarding groups, missed meal at landing.

Was a good flight. On time. Was full and all went well

You could have been ON TIME! And I was miffed because I spent an extra $82 to get my seat and the steward put a woman from the back in my aisle for nothing because her movies wouldn’t work. I’ll try that next time and save $82!

The weather caused a delayed but I was impressed how United did everything they could to try to get us out which included bussing us to the plane doing a Hardstand and bringing us to the plane since the fog was too thick to tow the plane from the overnight stay in the cargo area.

Crew was wonderful and attentive. Chris (I think that was his name as I was seated in the back in 52F) was amazing and funny. The captain was informative and did everything to get us to Denver as close to on time as possible. Bags came quickly at baggage claim. Online check in would not allow me to change my seat 24 hours ahead of time with dozens of seats showing open and I really do not enjoy being in the back of the plane for long international flights.

As no headphones/ ear pieces in back of seat for entertainment system, would have been to been offered rather than asking & waiting a long time. I know we are in economy but cost of ticket was high.

Flight got delayed due to a technical issue, but they were quick to find an alternative airplane.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

The main flight was OK but the second flight was chaotic with delays

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

All the British airways staff were very helpful and friendly. Every thing was very smooth running from checking in boarding and arriving 40 minutes early. Which is a brilliant start to your holiday.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.
