I’m hoping for WiFi included. Everything else was very good

I’m hoping for WiFi included. Everything else was very good

All corners have been cut and it’s a cheap experience that no longer is distinguished from most other cheap airlines

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.

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

it would good to have at least something to drink...

Everything was fantastic except the Iberia website and app… they left a lot of questions and induced much stress. But once on the plane, all was awesome.

Everything was great, except the food, which could have been flavorful.

Seating was very tight and not comfortable. Would rather pay extra to get more leg room. Overall, the flight was not as nice as expected. It’s comparable to flying Spirit Airlines or Frontier airlines in America. Even as a budget airlines, Iberia should at least serve water or light snacks, especially for international legs, no matter how short the flights are. We were flying from London, Heathrow to Madrid Spain on a 2-hour flight without offering water, unless you want to pay for the water.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

Changing the flight with app and customer service was very difficult and poor .although I h ad a ticket and seat number still had to pay more money as ticket not transfered. Couldn’t buy another ticket for my daughter on my booking too. Customer services’s appealing. My daughter was ill and noine cared.

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

Only two check in counters for online bag drop, economy and premium economy clients, NO management supervision whatsoever, no announcements, whilst Business and first class had three check in counters operational, with the bulk of clients flying economy on a 747…..very poor service indeed. Stood in a queue for two hours to check in!!!!!! The flight crew were equally indifferent.

Terrible. This airline will cancel flights at very short notice.

Plane was old and the persons chair in front wasn’t easy to move up so he had it back most of the flight including during meals. The touchscreen was not working well and selections weren’t good. First time on a flight I really had a hard time finding something to watch. The crew was great and without them, it would have been a bust. Pilot got us there in record time.

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very Stress free Lounges were superb. Crews were caring. I loved it.

The FA told me that the dinner was vegetable curry which turned out to be vegetarian (tofu) which I don’t care for but that was the only disappointing part of my trip.

Entertainment catalog certainly needs an upgrade to include better and latest content. Food was not good at all - they need to cook something edible. Five starts to the crew and on tim performance of British airways though!!

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

The flight was nearly empty so we were welcomed to spread out and relax. There was some turbulence but nothing too scary. The crew was lovely!! They engaged in conversation and were very friendly! The food is terrible!!! Horrible wooden utensils, they barely pierce the food or cut anything. I sat in basic economy and was very comfortable. Customer service at the desk was polite and helpful.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.

This was an American Airlines flight. The crew were very unhappy and quite grumpy. Abrupt to the point of being rude. The food was dreadful. Indeed the breakfast was in edible. I will avoid AA at all costs in the future.
