Very fast boarding. Crew members were super nice. I loved it!

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.

Left on time, arrived on time, despite weather, excellent service and food

temperature was too cold there should be free blankets, seat are very uncomfortable, entertainment is limited.

It was fortunate that the flight arrived in London in accordance with schedule, and the luggage was promptly transferred to the luggage carousel. However, I find it concerning that even minor issues in economy cabins are prevalent within the industry. American Airlines, in particular, appears to have the least legroom and feels more crowded due to the proximity of neighboring passengers. Additionally, the crew’s adherence to protocol is inconsistent. While they may enforce certain rules set by the FAA on a select few individuals, they often overlook numerous violations, such as failing to reset seat recline during landing.

Good Poor. service onboard No food. Low quality for economy plus

Easy and organized getting in and out of the flight

It was hidden that I needed a special fee to bring my guitar on. They charged me an extra 69 euros at the gate and did not refund me the checked bag I paid for and the over head bag I paid for which I didn't use because I had to pay for the special guitar case. Criminal behavior. They were very unkind about it as well. Terrible experience. I'd like my money back for the extras I paid for.

Basic service for a decent price, all amenities are à la cart

This was a short flight. We sat in business class so we we were served a warm meal, which was nice. The flight attendants were very attentive, professional, and kind.

The flight was great; I don't see any area of improvement.

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

The flight was good. It arrived at Heathrow on time but then there was no transport to take us to the terminal. We sat on the plane for an hour waiting for a bus. I will avoid Heathrow if possible in future. The crew were very apologetic.

we had to walk up stairs to get into the plane--no jetways. Perhaps that's a problem not with the airline but with facilities at Heathrow, Glasgow, and Edinburgh. But it was inconvenient.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Excellent service by the flight crew, and the food was relatively very good compared to other airlines.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They can separate the young children from people who want to have a rest. It had lots of crying and loud noises from the children.

I had an awful experience with British Airways as they broke the handle of my checked in suitcase and when I went to complain they told me that this was not their responsibility. This has to be one horrible airline that does not take responsibility for the damage that they have created

Didn’t fly with them as someone had cancelled my flight
