Airline reviews

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

1.It will be better if sandwich is warm. 2.The food is too salty. 3.Breakfast needs some vegetables or fruits.

Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

I was told in Florence my bag would go directly to Indianapolis. I had to wait to get it. Then security in EWR was slow so I missed my flight as United would not allow me on the plane even though it was still on the tarmac and the door to the tunnel was open. I blame both Lufthansa and United for refusing to allow me on board a plane that was clearly still on the tarmac. Behind me two grandparents and their ten year old grandson were on same flight from Munich to EWR. They were refused to board the United flight. So we had to sit for 12 hours in airport until next flight. No compensation has been offered either by Lufthansa or United.

Flight was delayed and luggage was delivered day after arrival. In Bilbao they told me day after would be delivered faster if I went to Bilbao to get my own bags so I did. Wasted my morning.

Seating was average for a first class seat. It very modern. I expected better.

very small seats screen did not work . I could not watch anything for 9 hours

The food that was served was superb!!! Awesome snacks!!! Frequent drink service!!! To me, this was shocking. I took a British Airways flight from Denver to London for the first leg of my trip and the food was horrendous. Thank you for keeping us fed and satiated on such a long flight!!!!

The seating arrangement by having privacy screens would have been more appealing. If you sit in the business class, you pay for extra comfort and privacy. Other than that, the service was excellent and the staff very professional.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Flights were delayed but very last minute, also seats felt very squished on the second flight. Crew was very friendly and airplane was clean.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

I was put into business class. Wow! My flight attendant was great! The food amazing’

The gate at London Gatwick had confusing signs for the different zones and the staff seemed harried because people didn't know when it was their turn to come to the desk. Plus, with there were too many carry-on bag travelers, myself included. The charge scheme for checking bags is frustrating. If you travel light, you want the freedom to leave as soon as you deplane. When you are forced to gate-check your bag simply because the flight is fully booked, you lose whatever time you'd hoped to save because you're still stuck waiting for your bag to come off the conveyor belt.

Safe arrival. Improvement on Time efficiency Effective Communication will be great.

Not so good with their baggage handling as they damaged one of my check in luggage

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

All went well on the flight, not happy of course with having to pay for a seat and in hold luggage of £50

They removed our booking without telling us. Cost us thousands to book last minute

The decided to just remove our booking without telling us. It ended up costing us thousands
