allow plenty of time for security check. Take all liquids, cream, make- up, foundation etc. out of your carryon luggage. a lot of travelers had their luggage pulled over for open bag check. This slowed down the screaming process considerably and caused me to lose my flight.

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

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.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Flight LIN MAD. Checkin was fine (but I must admit that being a Platinum member I skip the lines). Security was fine (they have the new machines where you need not take laptops or liquids out). Longe was OK (BA). Boarding was a mess, the boarding gate personnel were rude and some should simply not be in a customer facing position. Flight in itself was fine, usual Iberia European coach. We were on time and actually time to deliver luggage was better than normal for Barajas

Bad business class. Staff totally not helping. Lights and chargers not working

Great food, excellent service. Did not manage to make wifi work but in a flight of less than an hour it was not a big deal

Very well, except that my luggage didn’t arrive in the corresponding flight, but they brought to me the next day.

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.

The boarding was a nightmare. Iberia would not let me check in in advance. They then refused to issue a boarding pass in Paris and said I would get the boarding pass in Madrid. In Madrid, there was no transit desk, no help. I had to run around and find someone to issue the pass. I only had an hour and risked missing the connection. Only at the gate did Iberia tell me they were overbooked and had downgraded me. I was stressed, exhausted, almost missed the connection because of Iberia’s conduct. Unacceptable.

When having a connection at Madrid, it’s extremely confusing. You must travel from your arrival gate, all the way down stairs to a security check point, go up stairs, then downstairs to another security check. Then make your way to your gate. All the while traveling through a “mall” inside the airport which makes it difficult. 10/10 don’t recommend connecting flights through Madrid.

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.

okay, will recommend from PR to Madrid, faster turn around

I liked BA land team for boarding, the food, entertainment should be considered to be improved

My flight was late. We stayed in aircraft one hour 😩

Flight delay and can’t much help passenger do the change connecting flight.

This was a HORRIBLE experience. I booked a two-leg flight from Reykjavik to Istanbul. My first flight ran 3 hours late and I then missed my flight to Istanbul. British Airways put me on a Turkish Airlines flight to Istanbul. No harm done, right? Wrong. The Turkish Airlines flight turned out to be overbooked. By the time I learned of this, British Airways closed their help desk. To add insult to injury, they helped one person in front of me before casually putting up a closed sign even though they knew I was stranded (their fault!) and needed help. I ended up spending $1000+ out of pocket to clean up their mess (including the flight to Johannesburg I had to rebook since BA delayed me so much) and haven’t heard a word about reimbursement. I have never had such an awful travel experience in my life. I know delays happen, but they need to take care of their passengers when these things happen, not leave us stranded in a foreign country in the middle of the night with nowhere to go.

The seats are incredibly uncomfortable. My luggage didn't make it on my flight from London to Nashville.

5 days later I have not yet received my luggage so terrible and unacceptable

everything on the flight was a great experience except the food could have been better!

The seats were uncomfy and the food tasteless, crew clueless

Easy and quick check in, clean and nice seats. Overall excellent experience.

My problem was with the onward connection between London Heathrow and Washington IAD. The flight was several times changed.
