Needs faster boarding procedure. Not their fault but should still take into account indifferent flyers.

Needs faster boarding procedure. Not their fault but should still take into account indifferent flyers.

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

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

Great : The crew was awesome ♥️ To improve : - The rice in the "Rice with chicken" was rather s kind of rice pudding, not good at all - No power outlet to charge your phone. 😒

why can't planes be boarded from back to front?? everything was great otherwise

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

For what we are willing to pay for international air travel, our experience was very good. We had no problem checking in, we had very little wait time at the AA counter in Madrid, and the staff in Madrid were very helpful. The flight crew was helpful and courteous, the plane was on the newer side, and our assigned seats were together without us needing to purchase them. The flight took off on time and arrived early. Overall, it was a pleasant experience or as much as could be expected in economy for almost 10 hours.

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

Boarding was easy, the flight left on time and even landed 20 minutes early. The food was plentiful and really good! The crew was kind & helpful. Overall it was an exceptional experience!

Flight to get to Barcelona was cancelled and then the next flight was overbooked. Cancelled the entire trip and went elsewhere. Fighting with iberia to get my money back. Ill never book this carrier again!

The flight was safe, confortable and convenient. Thank you. I hope to come back soon!

Nice to fly out of Orly smaller easier to navigate airport. Being able to receive boarding pass well in advance of trip was comforting to know all travel was in order.

Liked. The check-in was pretty quick as they had 5 desks working.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Boarding was smooth and quick. Flight departed on time. Equally evacuation upon landing was from both the front door and the back doors. Bags were on the conveyor belts before I got there. Excellent service.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

It would have been better if I was not ill so I didn't go and I didn't come back and I could not transfer my tickets to a later date as Ryanair stop flying from Manchester at the end of October till next year

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

Passengers next to me insisted I change seats so they could sit together. I had to frequently move so that when the sear belt sign was on I was in my proper seat! I was returning from helping my mum with my dad's things after his sudden death and didn't feel like arguing with the other passengers.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

The table at my seat was dirty, the crew was nice, the boarding was swift. An average Ryanair experience but this time the plane was not properly cleaned between flights.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

I do not understand how BA takes coach seating and has people paying for business class. There is no leg room, seats don’t recline and no entertainment to be had unless you brought your own.

It's useless to complain about the space and the back of the seat, making you sitting vertically like a candle. it's your business model. The "food" - there is no food. But I don't care about the food. It's the seating.

The flight was comfortable and the attendants were readily available and helpful. The food needs to be improved.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

Overall, it was basically good. No serious complaints on my end.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The aircraft was okay and the crew were friendly, but the seat space felt too tight and the food could be better. Overall, nice service but room for improvement.

The flat beds. Other than that, the place was not clean.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.
