An average flight experience. For our transatlantic portion, they provided a main meal and two snacks. However, the food was not very tasty and the drinks far too small and infrequent for such a long flight. The regrettable part of the flight was that the toilets were extremely filthy. I feel this is unacceptable.

An average flight experience. For our transatlantic portion, they provided a main meal and two snacks. However, the food was not very tasty and the drinks far too small and infrequent for such a long flight. The regrettable part of the flight was that the toilets were extremely filthy. I feel this is unacceptable.

Both flights were delayed. I lost my connection on the way back. No voucher or anything was givenx I had business ticket and no support to make it on time. I got to the door running 5 min after they close. Food really bad. Breakfast in business was worst that I what I remember in economy. Even though I have accumulated many miles, I don’t think Inwill keep buying Iberia. I am a frequent business traveler.

The food is really eco only level. Breakfast was shameful. I am considering to stop flying with Iberia. Business prices are as expensive as other companies with much better service.

Why no entertainment? Also water should be free, it is basic human right.

Late boarding. Delayed departure leading to rushed connection at Madrid Barajas. Not necessarily Iberia's fault but delay loading cargo didn't help.

I can’t comment on food as it was necessary to buy it. No entertainment.

Took too long to tak off but besides that it was good

They made my flight a disaster they had me pay for bags that I already paid for through Iberia airlines and the hostesses were super mean and racist they just turned my vacation to a total nightmare and disappointment in fact they even had me rethink even no to go to morroco ever again even if my whole stay at the country was so nice and fun and perfect but anything at the airport and with the airline was a disaster do not recommend will never take a flight with them

All went smoothly, no problems; friendly crew. I would have appreciated a head pillow ;)

Staff not so nice, very dirty bathrooms, things in the hallways, food was not very nice.

The whole flight was coughing and farting all the way. It was impossible to breathe. If people are traveling sick they should either not be allowed to fly or made wear masks

I will never fly vueling. 1h30 delayed, connexion missed with the crew closing the boarding in front of us. 40 people missed the Barcelona-Orly connexion. hours waiting for rebooking and hotel.. inadmissible

3 hr flight from Barcelona to Gran Canaria. Ŵent according to plan No issues with staff oŕ flight. Many people includiñg us could not get luggage self checķ in termìnals to work. Had to wait in check in line.

The communication about the delay could have been better before and during the flight. Also, this online form could have less bugs. It is almost impossible to type in this window.

Boarding was very poor as the flight was initially delayed. We were told the flight would be at 21:40. We were with our 10 month baby who was sleeping. I received an email from Kayak which said the flight was now due to take off at 21:04. When we checked the screens at Gatwick we were told the gate was closed. The lack of communication was extremely poor and we had to run with our baby and there were many other passengers, including elderly people, also running to the gate. When we got to the gate, the staff had no reasons for the poor communication.

They stop online checkin above a certain capacity. We had to go to the airport to check-in at the desk. Or was offered to pay 7eur extra. Rip off.

It was a short flight but the seat was very straight. I didn’t need any service, but wifi was not available. In resume, a normal service. Nice, the punctuality. Thanks

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

Last time bucking this company if I would know I wouldn’t do it, they made me lose my flight

I liked the regular updates and appreciated the automatic online checkin which didn’t work for our Vueling flight so I had to do this myself.
