I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

A bit rush for transit. Food and entertainment are not available

Wonderful and fast TSA checkpoint. The line was fast and our gate was close by

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

headphone jack didnt work for the first flight and not much variety

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.

My luggage got lost and until today there is no solution to the problem. It's still missing

I am writing to demand an immediate refund and compensation for the absolutely unacceptable experience I endured with VUELING this week. On Monday, my flight was canceled, and despite this, I have yet to receive any refund. I was then taken to a hotel in a terrible location, where no food or even water was provided. The next day, I was rebooked on another flight, for which I had to personally cover an additional €50 in transportation costs—only to have that flight canceled as well. After waiting 10 hours, only 10 of us were offered alternative accommodations, while the rest were left stranded. We were forced to remain in this situation until Thursday without a single explanation or proper assistance. During this entire ordeal, we were only provided with breakfast and dinner, while being charged extra for drinks. This level of treatment is completely unacceptable. I expect an immediate refund for the cancelled flights and full compensation for the inconvenience, additional expenses, and the significant distress caused.

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

Nothing. There was no flight. They cancelled the flight with no replacement about 9 hours before takeoff.

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

Boarding with some sense and communication. It was a total free-for-all everyone coming all at once, no organisation of row numbers or priority.

Horrible, flight cancelled and had to come back the next day

Terrible. For clarity - this was the Level flight to Boston. Not Vueling. Would urge customers to avoid this airline. Gate agent was singularly unhelpful. He was argumentative, rude and went out of his way to ensure that every penny was collected for the baggage (which we realized given how early we were for flight we could have saved hundreds of dollars if we checked in on app). No onboard entertainment or WiFi. Half of the front section was empty because the seats did not work! Plane was falling apart.

No complimentary snacks, but I think that’s a standard in the USA. There were loud drunk Germans sitting in front of us.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

I wish they could put the pre-tsa check on the tickets or global entry.

We upgraded to Business class paying approx. $1,300. Despite the upgrade, we were still required to pay an additional €70 for a checked bag. Furthermore, we were informed that another €70 would have been charged for our carry-on bag, as it was 3kg over the limit. To avoid this, we had to move clothing from the carry-on into the checked bag, which was both inconvenient and frustrating. Given the significant amount paid for the Business Class upgrade, we found this treatment to be quite appalling and disappointing. We expected a higher level of service and consideration for our luggage, and this experience did not meet those expectations.

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 plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

The flight was cancelled due to tech problem with the plane
