The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Read more United Airlines reviews

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

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

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?!?

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.

My experience was medium staff where great I dislike flying in triple 7 seats very uncomfortable and no room on jet all the rest of the flights where great

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

I’m still missing my bags. I’m soo frustrated

TAP boarding gate agents singled out Group A line to gate check all carry on bags …. Supposedly because of lack on bin space. BUT ALL OTHERS WERE PERMITTED WITH CARRY ON BAGS. Additionally so many passengers entering the plane after us were permitted carry on bags. And when the plane was fully loaded, there was a number of open spaces in the overhead bins. I WILL SEARCH OTHER OPTIONS BEFORE FLYING TAP AGAIN

Our flight was canceled for a reason that suggests gross mismanagement. We were re-booked for a flight to a different airport.

Worst: long walk to baggage claim Best: left on time

Got in on time. Food was the worst ever. Comfort was terrible. Check in was incredibly bad.

The flight schedules are better than some airlines. Their website is terrible, it doesn’t store any information so every time you fly you have to re-enter the data. The flight was late taking off but we still got to our destination on time.

Flight delayed by >1 hour. Long boarding involving riding a shuttle to the plane.

When I tried to enter my identity details, your app told me information was missing but did not highlight the missing data. This was frustrating. Also, there was an unexplained delay of about 2 hours in taking off. This was also frustrating. Otherwise the experience was good.

The flight was delayed without any type of notice. After passing through the gate, people were lined up at the passages boarding bridge standing for about half hour with no clue when they can board after ‘boarding’. No explanation or indication of the new departure time. All you can do is standing up and waiting.

Not online or self check in, sent emails in Italian language ,not recommended.

You idiots…ITA cancelled our flights one month out and we had to buy new tickets at a much higher price. You stiffed us by not refunding the cost of the insurance. I’ll never buy through Kayak again.

Premium Economy was average for class. Seat comfort was just okay. Crew was attentive. Checkin was fine and moved quickly. Boarding process in Rome was not well organized.

It was horrible the woman next to me was sick and I asked if they would change my seat and they said that they didn’t have any available. I sat next to this women for 9 hour and now I am sick .

We booked and purchase our seats in February for a September flight. We choose seats then also, did the online check in on the app the day before and all was fine. At the airline check in they charged our seats and we were not even sitting together after paying for business class seats. They separated us with no explanation and would not change them back. I was very upset. On the return flight, they tried to put us on standby! When again, we purchased seats in February for this flight. The plane was old and smaller and the business class seats were not comfortable like the flight from NYC. Flight attendants were hard to find once the first meal was served, luckily the flights were smooth.

Not boarding 60 minutes late. after getting bumped to this flight because ITA do not hold a flight for five minutes as the fight to the connection was 45 minutes late

Crew was good. Very nice staff. Wine was good. Problems- no AC while waiting for takeoff. Long wait so we should have been more comfortable. No water for quite awhile. Food should have been better for an Italian airline. Chicken was pressed rounds of processed meat- not tasty. We had only one hour for our connection- ran through airport- plane waited for us and staff was helpful.

Flight was cancelled and other being told it was cancelled there has been no other contact.

Poor , i missed the next flight to new york . We stayed inside the plane for almost 30 or 40min

Everything was fine except the food. They really need to work on the quality of the food.

The flight was cancelled due to tech problem with the plane

I pre-ordered my meal and did not receive it. The seats are very old, uncomfortable and dirty. The crew was excellent and made my stay on board comfortable and enjoyable.

It was great. The airline staff was very friendly. The FRA security was a bit harsh doing their job but friendly overall.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

Eet late informed about delay of more rhan four houts

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

My schedule flight was rebooking and changed to Chicago, then I did not used the flight from Dulles to Savannah

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

Boarding was chaotic. Glad we were group 5 and still had cabin storage available when we boarded. I was expecting crew would get our carryons at the gate since theyclaimed it was a full flight.

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage
