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

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.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

I feel bad, but Swiss airlines is not an airlines I will ever fly again. Their cabins are basic, seats are extremely uncomfortable, crew is a hit or a miss with service. What's worse is how they make you feel they are there to make money and not make your travel needs be met or make your travel a pleasure. They charge for 2nd bags, seat selection and felt like a budget arinines frontier/spirit airline attitude and approach. Their business class is from the early 2000s, basic. Additionally, planes going to India, are old, falling apart and not maintained. Even the crew mentioned this is typical of the airline having older planes going to India. Panels detached and loose or stuck with duct tape, seats scruffed up and dirty, seatbelts roughed up. The scariest thing was when I saw a window panel next to where I was sitting loose and dangling. The crew mentioned it's only cosmetic and assured the integrity of the plane was inspected by the maintenance crew. This is where they confessed about planes going to India being old. I UNFORTUNATELY would NOT recommend Swiss airlines to anyone and will NEVER fly with them again!

The ANA crew and their members were all extremely nice and caring. Shout out to the crews for working on Christmas and New Years. Y'all the real MVP

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.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

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! 🤛🏽💗

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

This flight didn’t happen because AA agents didn’t let us board the flight

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

The service and food needs to improve to catch up with other international flights

Would have been good to have a meal since it was a 5.5 hour flight

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.

AA is always pretty solid. Was on time all the way around today so can’t complain!

Great thanks - a whole row to myself. Good food but film selection not great.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I liked the duration speed while in the air but that is is for positive things to say. The service was over 3 hours late, staff not very friendly (probably because they were also late to the destination), uncomfortable seats and disappointing food options

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

Was very unhappy with the entire process, from check in to boarding to the comfort of the flight. Did not enjoy the flight on Level.

Overall a great. However, the seating is way too narrow, for guys with any shoulder width. Luckily the crew moved the guy next to me, or it would have been miserable.

The staff on our flight from Charlotte to Boston were very friendly.

Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

The flight staff was excellent, one of the best I've had. Food and wine was very good and seats very comfortable. Luggage came out pretty quickly too considering the number of passengers. Also, excellent internet. The only thing that could have been improved on was the choice of movies -- kind of limited and not great selections.

The plane was not well maintained. The entertainment system didn’t work properly, eg moving map. Many of the seat controls did not work. Cabin temperature fluctuated considerably during the flight. The seat allocated was poor, it was noisy and offered no privacy. The perfume in the toilet triggered severe allergies. Crew was very goid.

Seats are too tight. Small space for long flights very inconvenient.

The flight was delayed over 3 hours and at the gate, we waited for an hour to start boarding. The gate lack of communication with the passengers was atrocious and when asked they even said they didn't work there and were just standing in for someone else so they couldn't give us an information about the flight status. The crew did not offer blankets, pillows nor headphones.

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

Happy and nice crew and the atmosphere is very easy and calm. I got a wonderful travel with UA this time

Terrible experience. Should be a short simple flight from San Francisco to Palm Springs. Disgusting insult that United Air doesn’t have a cabin crew ready to receive a plane that’s already an hour plus late in departure. Lots of misinformation along the way from cockpit and crew. Definitely unimpressed with both union and management.

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

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.

I never made this flight but the staff helped to get me rebooked (see previous review)

No land services during boarding, specially while moving from terminal to another

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.
