Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

Flight was fine - however my husband's checked in case was damaged, and mine still has not arrived

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

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.

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

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.

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

British Airways changed flight times after booking, allowing very little time between connections. We had to rush to barely make the next flight. They also ran out of certain vegetarian options during our 10-hour flight. Crew was fine, but overall a very unpleasant experience.

Being a platinum member and having reserved an exit row I was bumped into a middle seat which should not be allowed. On top we landed 10 minutes early to wait 45 minutes on the tarmac at Heathrow. I used to love Iberia, loving it less and less

I want to ask kayak company are dealing with kiwi.com s r o I have bad experience for this.

Old plane, sold out on snacks, just trashy seats..broken..etc

I liked the movie selection and the speed getting the luggage. I did not like the fact that for premium they did not have a personal kit with toothpaste, I travel all the time in premium economy and bussiness and althought the kit might bot be the same at least you have the smalles kit in premium economy. I did not like either that because i was in the last row of premium economy nothing made it to my seat. They run out of the food I wanted ( it is a surprise because there were only 6-7 rows. They would run out of orange jouice were thy were passing water/orange juice around, they run out of some alcohol. I am undertand running out of it but I don’t understand why mot getting kore. The service I received in row 11 was different from the service in rows 7,8…. Also the screen on my tv was broken. It did not respond to touch. So, in conclusion, if I compare my flight going to Europe with an American airline plane in premium and the one with British, British expereince was significantly much worse. This company is declining fast.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

horrible! after going through hell and back to get a flight home after my flights got cancelled I also had a delay of 2hrs stuck inside the plane because of some technological problem.

The luggage is still in transit and the ground staff at Heathrow airport very rude and uncooperative. If I was you, I would fire them straight away. Bunch of incompetent folks.

British Airways keeps canceling our flights. They have lost my trust in using their services again. I understand rescheduling once but twice? I am now arriving at home 36 hours later than the first flight that I booked.

Excellent except for checking in at Madrid Airport. Waited in line for over an hour and a half. Not enough ticket agents available and they were moving those with earlier flight times up in order to get them through. People were not happy. Staff did their best to explain, but just not enough to meet the need.

I went to check in my luggage at Madrid airport and not a single service kiosk was open for me to check my luggage! I had to scramble to figure out how to my luggage home! Luckily, the airline of the person I was in Madrid with did have workers there and they checked my luggage in with thiers. I still have to figure out how to get it to me since we live in different parts of the USA. There was no reason why I shouldn’t have been able to check in my luggage at the Madrid international airport. I do not trust British Airways.

The terminal for this flight, 4S, was INSANE. So many Iberia desks, and it wasn't clear which ones were for which destinations. When I checked in, I asked if I could check my bags to LAX, my final destination, but was told no because my next flight was with another company--I would have to gather my luggage and then deposit it again in London. Annoying, but okay. Then I went through Security, where I was asked to open my luggage, berated for having water (which I offered to throw out), and just generally hazed. After Security, I went up and down countless escalators and then boarded a tram, which literally went miles. Following the tram, there was ANOTHER escalator and ANOTHER line, this time for passport control. At 10:25, I told officials there that I was on a 10:40 flight, but nobody seemed concerned. So after clearing passport control, I RAN all the way to the gate, where my boarding pass was scanned, and then ran along the gangplank. At this point, I expected to board a plane, but what I encountered was a STAIRWELL, with steep stairs leading downward. Astoundingly, I didn't see any elevators or escalators. I lugged a suitcase, large bag and jacket down three to four flights of stairs, expecting to board an aircraft at the end, only to encounter a bus outside. After all the hoops we passengers had just jumped through, I was floored by this. And because the bus driver was waiting for other confirmed passengers, the rest of us were standing on the bus for at least ten to 15 minutes. Once the bus FINALLY set off and then dropped us at the plane, which was sitting way out on the tarmac, we all had to cart our luggage and bags up ANOTHER steep set of stairs onto the plane. In 100-degree heat. Parched from the physical marathon I had just endured, I was thinking that once we were in the air, the flight attendants would pass out water. Instead, they went down the aisle asking if anyone wanted to order and pay for a drink, but they never asked me or many others if we wanted anything—they picked and chose passengers to ask. I raised my arm to try to get their attention, as I was desperate for some water, but they were avoiding almost all eye contact with the passengers. So I arrived in London completely dehydrated. Then I went to baggage claim. After waiting for about 20 to 30 minutes for my bags and not seeing anything that resembled mine, I started looking at my phone. That's when I saw an email from Iberia saying that there had been an incident with my luggage, and that my luggage had not made the flight, even though I had done the Madrid baggage drop in good time. Also, if I hadn’t checked my email, I don’t know how I would have found out that my luggage was missing, because there weren’t any reps at baggage claim. When I spoke to the Iberia representative about it, she said that the luggage would be arriving on another Iberia flight at 3:00 p.m. that day, but I was scheduled on a Virgin Atlantic flight departing London at 3:45, so picking up my luggage at 3:00 p.m. and rechecking it wouldn't be an option. After everything that had already happened that day, this was really disappointing. I didn't see my luggage again for two days. Honestly, it was just such a bad overall experience that I can't imagine flying Iberia again. And it was surprising, because earlier in the trip, I had been on the Renfe high-speed train from Barcelona to Madrid, which was a really good experience, so I had high expectations for Iberia. This could have been an aberration, but since it has been my only experience with Iberia, it is my only reference point.
