the seats were bad and uncomfortable and the food was not tasty.

The crew was amazing. I appreciate the level of professionalism in the Iberia crew.

A more organized boarding experience and better food would have made the experience better.

Flight cancelled, lost a day of travel where we were trying to meet friends we couldn't meet. Iberia website is very difficult to navigate and has lots of dead links. If you do not speak Spanish it is even harder. Tried communicating on their WhatsApp and that was also close to impossible. We were told we'd be compensated 150EU's for this cancelled flight but there is no avenue towards rectifying this issue. I've had to take it up with my credit card to contest the charges and not pay for a flight that didn't happen but doubt I will ever be reimbursed for my two Ubers to the airport where we never even departed or the 150EU's we were told we would receive. I would never fly Iberia again. Clown show.

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.

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

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!
