Thankful for 2-4-2 economy seating. Food was ok. Free beer & wine in economy was nice. Served hot dinner, mud- flight snack and pre-arrival ham sandwich. Seat with pillow & blanket. Reasonable movie options. Overall, a good experience. IBERIA APP is terrible terrible terrible.... needs to get upgraded to equivalent of TAP Airlines App. No option to bid or request an upgrade. Very disappointing.

My luggage did not get to my Miami destination/home. I am waiting for it 24 hours later.

The only comment I have is why do you sell snacks on board? They should be free. When we take domestic flights here in US, our snacks are free. Also, please communicate with me in English. I received so many emails way before my flight that were in Spanish that I had to ask my son to interpret for me. You should be WELL AWARE if the customers you are communicating speak the language, it does mean that we speak and understand Spanish because we are traveling to Spain, NOT NECESSARILY! Thank you!

Flight was delayed by well over an hour. Communication was terrible.

I like the team but I don't like the food you provided with money. I want free food and free water.

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.
