Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

I’m an Iberia fan but this time They dropped the ball. I went from ALC to MAD to LHR. Boarding in ALC was by group… to get you in a bus. Then we sat for almost an hour when most people had connections. When we landed in Madrid we did so and they put us in another bus almost like if they wanted to make people lose their connection. We made ours by the skin of our teeth but our luggage did not. And on top of this we had to listen to the pilot bragging about Iberia being punctual. To be true we made it on time to LHR but we are Still waiting for our luggage

I have to compare it to the AA flight back home. AA was a little better. Perhaps it was that American English is my native tongue. My seat on AA was newer and more comfortable. The food was a little better. The entertainment was much better, more movies worth watching. The sound was lousy on both.

Excellent liked business class except wife’s luggage was lost on 10 Hours connecting flight to Miami and we were priority! 1:20 layover! Expect better From American Airlines partner

Service was good , communication and emails were in Spanish though I booked in English , end up figuring it out but also flight was partnered with air maroc and I had to call them to check on not Iberea doesn’t make sense

In general, I've had excellent experiences with Iberia flights and will continue to use them. In this last flight there were two things that didn't go right. I didn't get the kosher meal I had pre-requested when I had checked in on-line. Things worked out OK as we ended up eating the fish and vegetarian choices, which were really good. The other issue was that some movies for me and my wife started fine but after 8-12 minutes the content just switched to something else. The flight attendant reset our entertainment systems, but the problem persisted. We ended up choosing other movies/TV shows that did work fine.

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.

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.

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

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

I liked that we got there safely. I disliked long delays, gate and ticket agents incompetence and apathy and having my luggage lost. Five days later I've yet to get anything more than a generic apology from British Air. Luggage yet to be located, much less returned.

Long line with check in at the DIA British Airway counter.
