Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Rude Iberia security crew at the Madrid terminal. No Iberia officials to be found to redress complaints at the gate. No supervisors. Nothing for processing upgrades at the gate Iberia app did not work to let me upgrade my options to higher classes. No water was offered on a hot day in Madrid. Madrid airport air conditioning was so weak that people were sweating. Never book on any airlines that codeshare with Iberia.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The entertainment system did not work. And we waited 45 minutes in our seats after we landed before we got to the gate

It was a pleasure definitely going with Iberia on my future travels

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

In-flight entertainment was. It working for the entire 12 hour flight! Unbelievable! At least provide free wi-fi so people could use their phones.

Check in was awful. Missed our flight because we waited to check our bags for over an hour. Only one or two agents available. Plan on 3+ hours if you fly out of Madrid. Won't use this airline again.

Flight were delayed which made me miss all the other flights. Bags are still missing from 2 weeks ago. This airline is worse the Spirit Airlines!

Web site needs improvement Plane was clean and modern Lay Flat beds were hard and not to comfortable (business class )

Overall, everything was fine—the service, the food, and the entertainment—but the boarding process in Lisbon was a total mess. I’m not sure I’d fly with TAP again. It’s absurd to have to pay for good seats at the front of the plane only to board last; the overhead bins above your seat are likely already full thanks to passengers who boarded earlier—even though they might be seated at the back of the plane. I will think very carefully before flying with TAP Portugal again; it seems to me that they need to review their boarding process. I understand the logic of filling the plane from back to front, but the seats at the front are more expensive. Horacio Rodriguez

Boarding was delayed by one hour because cleaning and catering crews did not board the plane in time. Take off was delayed for another 40 minutes because of "rush hour scheduling". Vague descriptiion. My in-flight entertainment system was stuck initializing. The flight attendant indicated that they could not reset it without resetting everyone's system. Overall, a miserable experience.

Better leg room than expected in economy. Nice crew. Adequate bathrooms. Seat cushions a little thin, but recline well and have adjustable headrests. Best value. Liked having nonstop from ORD to Lisbon.

Excellent! Flight left a bit late but overall a pleasant experience.

On both flights, TAP Air Portugal messed up the seating choices that I paid for. They acknowledged that I had purchased seating, that they were errant in ensuring my choices, but told me nothing could be done about it. When I asked to be refunded, I was directed to "talk to someone from Air Portugal" Mon-Friday, and then I was dismissed. No help, no phone number provided to me. I was very annoyed both times and feel cheated.

Delayed departure Madrid to Lisboa and my luggage no arrived

TAP boarding gate agents singled out Group A line to gate check all carry on bags …. Supposedly because of lack on bin space. BUT ALL OTHERS WERE PERMITTED WITH CARRY ON BAGS. Additionally so many passengers entering the plane after us were permitted carry on bags. And when the plane was fully loaded, there was a number of open spaces in the overhead bins. I WILL SEARCH OTHER OPTIONS BEFORE FLYING TAP AGAIN

The flight from MAD to LIS was absolutely horrible since they didn't allow me to board the flight I had paid for. It turns out TAP has a rule hidden deep in their terms of services that if I miss any of the flights in my multi-city plan they will automatically cancel all the remaining flights. I don't know if this is unique to TAP or common practice, but it seems quite ridiculous that I pay for a flight plan and due to unforeseen circumstances miss one leg of that plan that all remaining plan flights be terminated.

Great airline, new, comfortable and quiet planes. Plenty of leg room and state of the art entertainment system. The big downside is the connection in Lisbon. The airport is small and a bus is needed from the plane to the terminal. Is a mess, takes a lot of time, nobody gives an explanation, boarding zones are not honored, etc.

I had the best flight crew I have ever experienced in all my years flying with AA. I would specially like to thank Till Tatum/96038 for her kindness professionalism and outstanding service! My son turned 8 years old one day before our flight and she went out of her way to make him feel so special. We will never forget this flight! The whole crew made a special card for Frankie’s bday and it really touched our hearts. He will never forget it and neither will we! Thank you with all our hearts! We hope to be on more flights with Till Tatum and this amazing crew.

The middles seats on the 777 airplane are very small. I am only five feet tall and my knees were touching the seat in front of me and the is no leg room if you have a person item under the seat. The food was horrible, spicy sauces, tasteless bread, and wilted/brown lettuce. Keep it simple. The staff was mediocre., one minute loud and chastising, and the other friendly. We liked how clear and easy to understand the entry process in to the US was.

Everything was fine except the end of the flight. We spent more than an hour circling around Miami due to weather conditions. That was not good.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

Terrible. Extremely expensive. Monitor wasn’t working the whole flight 11 hrs and American didn’t offer anything. Change of seats, wifi etc. I’m expecting q compensation from the airline

I wish that we wouldn't have to go through TSA again on connecting flights.

My baggage went to Dallas and not to Philadelphia. Do I need to add anything else?

While going to Porto Portugal my luggage was delayed for 3 days . While coming back My flight was delayed and missed my connecting flight . No compensation for delayed luggage. Not a happy experience .

The crew was very pleasant and professional. The boarding process in Madrid was a bit chaotic. Also, boarding a bus to get to the plain is a royal pain. Clearing customs in Charlotte, then get your bag and rechecking it, then going through TSA again doesn’t make any sense.

All four segments of my trip on Iberia were late for various reasons. No apparent effort to stay on schedule. Never flying Iberia again.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Worst flight I ever experienced, what was supposed to a 7 hour flight ended being 13 hours on a plane with no ac and the worst cabin I have ever seen. Never again.

Excellent crew, food and service. Boarding via bus is always a pain but overall really good

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

Horrible see last review they lost my bag had to sprint to gate no inflight wifi

Mediocre. I didntneat for more than 9h. Pregnant and diabetic. 0 care from The crew.

It was not Iberia. It was with United. It was great!!!

As compared to our beginning flight to Madrid this flight was light years better in every category! Highlights were the top notch crew, service and food. Our first experience with Iberia was at two opposite sides of the spectrum. Thank you for an excellent return flight to Chicago - O Hare!!

The flight from Dallas to madrid was delayed for 2 to 3 hours, the flight back from Dallas to Sacramento was fine , but there were 5 gate changes within the span of 2 hours, last one was in a differny terminal. Flight and crew was okay

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.

Well unfortunately our connecting was cancelled and next flight delayed. Was in airport 9 hours. Flight itself was good. I’m sure it was a FAA problem.

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.

My seat was broken and unable to fully recline. My USB power point was not working and nor was the one next to me. It made a 12 hour flight feel a lot longer.

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.

Tv didn’t work till the last hour of the flight. Staff was rude and on a couple occasions was arguing with each other. Food was possible the worst I’ve had on a flight.

Coach seats are too tight. Seem designed for small people. Food different but OK. Staff helpful.
