Basic service for the basic price. Efficient and cost effective, so ticked all the right boxes.

Not constantly changing the price DURING a booking. Felt like bait and switch.

All very smooth airside. Check-in counters were understaffed. The wait is too long. Only two, then three counters were open. Waiting time of 35 minutes is too long. Pls review your rota.

To complex. So many types of fare. This made the boarding a caos.

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

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Really like the idea experience on this airline I will use again

The pilot was professional and very good. The flight crew, very young and often looked flustered and overwhelmed. The seats were among the most uncomfortable in the air. The boarding somewhat chaotic. The price reasonable. Overall it was an average budget airline experience...although Iberia is not a budget airline. I fear if Iberia doesn't up it's game customers like us will go elsewhere.

Bad weather Excelent pilot Spoke British 😆on time seats small ad expected in a discount airline

It wasn’t great because the third-party from Kayak there was just no information about how to check in with Vueling. And the purchase of the ticket from under pricer just made everything really difficult. I’m unlikely to use Kayak again for these reasons.

It was fine, older plane with limited entertainment, otherwise fine.

the seats were so cramped you could barely move. it was difficult to eat when passengers would recline their seats. the seats were so flimsy and unstable that whenever someone got in and out of their seat, it bounced like a spring back in your face. the movies were nice. the food was terrible. even though the conditions were terrible, they tried to pressure passengers to relocate their seats to accommodate adults who were related and wanted to sit next to each other, even after the passengers expressed that they did not want to move for that purpose. on the connecting flight, the “service” consisted of items for purchase. even though the flight was only 45 minutes, once again passengers (including me) were pressured to relocate for people to sit next to each other. they couldn’t be apart for 45 minutes? this was much less compelling than being apart for an 8 hour flight.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.
