Very slow boarding, 1 hour late - uncomfortable chairs and crew barely speaking english even at the airport!

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

Airline changed our itinerary several times (3). The second time, we were not aware of it, we landed at 7:24 pm and the flight depart time was 7:40 pm. We were not aware of this change and the flight departed without us, that made us being placed on an even later flight which was also delayed.

Paper boarding passes needed, so you need to add the time at the kiosk or desk to get them at the airport

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

It was a long and boring flight with no entertainment and no meal only a drink and very bad bag of chips

The crew was super friendly and respectful, they made me feel well all the fly , thanks delta

The crew was amazing. The best in the last times. Great group of people.

Check-in was a total disaster, almos a full hour in the line

My experience it was okay but have many thinks to be better. For example the food, the comfort.

The crew was not kind , just doing their job but very cold people

The insanely long lines at customs were chaotic and stressful. They also created a lot of stress among passengers. Including fights and threats. The hot food I purchased was cold, barely edible. The check in staff and crew were nice and the pilot good but the overall experience was very disappointing. Passengers were still insulting each other upon arrival.

No frills airlines. Tickets were reasonably priced for a short-term booking. But comfort is a big issue.

It was just okay. They overcharged me for a checked bag because I didn’t know it wasn’t included in the airfare.

Very small dinner, NO breakfast. You have to buy an earphone.

Food was terrible. No breakfast. Will not use this airline.

I'm not going to travel with that airline again.

I travel on a monthly basis and I’m not a stranger to budget airlines. I never complain about anything, it just about adjusting you expectations to what you paid for and you will get, but these flights (2) with Air Europa Miami - Madrid - Athens were a terrible experience. Both flights had a significant delays and multiple gate changes. At the checking they used a hand scale to weight your carry in, it cannot be more than 10 kg , even it fit on size.Luckily mine was ok . The food was inedible. The staff service was ok, but you can totally tell they do not care about much and show little customer service culture. I think this was my last trip on Air Europa. Actually the price was almost the same than other major airlines, I just took this one because I needed to depart late at night.

Probably will never use this air line again. Rude miserable staff. Uncomfortable seats.

Well, I'm not too happy with the service a flight for 9 hours with only a cup of water or wine. Food only service you one-time I bind flights many different airlines and they make sure that you feel comfortable with the food and drink

Excellent with no delays and according to the time schedule.

The boarding was a nightmare. Iberia would not let me check in in advance. They then refused to issue a boarding pass in Paris and said I would get the boarding pass in Madrid. In Madrid, there was no transit desk, no help. I had to run around and find someone to issue the pass. I only had an hour and risked missing the connection. Only at the gate did Iberia tell me they were overbooked and had downgraded me. I was stressed, exhausted, almost missed the connection because of Iberia’s conduct. Unacceptable.

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

N/A - missed the flight because of the delay in flight to Madrid

Worst flight in years.. is not easy to flight 11 hours without entertainment onboard and the crew was not empathetic about it or even gave an apology for the inconvenience. Poor treatment to the passengers, and some responses where roughly given.

I fly to BNA with BA often and this was the worst experience. Arriving in nashville, check in was 1.5 hrs long in the queue with 1 very slow girl at the desk. When more staff came they only catered to priority customers. When all priority were checked in, instead of filtering from the top of the line they took the people from the end, the people who had been queuing for 5 mins vs almost 2 hours. The flight was delayed, for no good reason other than the staff took forever to do anything. At the gate there was zero organisation, we asked the crew what the delay was and they confirmed it wasn't the plane and it was the ground team. One of the flight attendants was one of the rudest I have EVER encountered, that man clearly hated his job, and people...I wish I'd got his name. Food was disgusting, seating was cramped. I've no idea what's changed in the last year but I'm truly shocked.

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 had assist travel booked in Denver to Manchester, but not listed in HeathRow, my daughter use a spare wheel chair herself for me , when going thro to board at Heathrow there was no help travel down for the ramp until a member of assistance stepped forward and insisted he would take me down the very steep ramp, seems he was the only person concerned with my safety.

Booked Economy Premium the 3 seats with my daughters and I, the seats should have been able to tilt back but it only one worked. the crew said they would report it but didnt seem both about our comfort on the return journey.#

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Using the media screen in economy class is a disaster

Liked - efficiency of boarding with 2 jetways. Checkin was with kiosks with helpful and plentiful workers to help with the process. Munich airport security was very automated, efficient and effective. Free wine and beer! Cons - food was only okay in economy class. Plane bathrooms could have been cleaner.

Prompt, efficient boarding. Clean aircraft and knowledgeable crew. Everything on time.

Lufthansa only flew me to Larnaca. I had to find my own way from there, and am out of pocket for a ticket and hotel expenses

It was terrible, I was denied to board the plane because I don't have Germany visa, but I don't know I need a visa because all I want is go back to united state and I don't need to enter Germany. When I buy the ticket and checking in I entered my Chinese passport information and I did not get any notifications that I need apply for Germany visa. This trouble is generated totally by Lufthansa and they don't offer any useful help to solve my issue which cause huge problems to my travels.

I had a family emergency and couldn’t board and I contacted underpricer to help me get a refund or just a flight adjustment as i would still be flying later that week, and that hasn’t happened. I will never book a flight through kayak/ underpricer ever again.

It never happened. Bumped 2 times then cancelled. 4 cancelled flights after that

Very good! Only negative was having to purchase water on a 2 hour flight! Felt even soda should have been free!

Missed our flight to London and we were put on coach seats to Munich.

I didn’t receive my luggage until day 5 of a 9 day trip. During a layover a crew member made a very insulting comment about where I was visiting and where my partner was from in England.

Attitude of crew could be more friendly and less stern and instructive.

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.

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

I liked BA land team for boarding, the food, entertainment should be considered to be improved

My flight was late. We stayed in aircraft one hour 😩

Flight delay and can’t much help passenger do the change connecting flight.

This was a HORRIBLE experience. I booked a two-leg flight from Reykjavik to Istanbul. My first flight ran 3 hours late and I then missed my flight to Istanbul. British Airways put me on a Turkish Airlines flight to Istanbul. No harm done, right? Wrong. The Turkish Airlines flight turned out to be overbooked. By the time I learned of this, British Airways closed their help desk. To add insult to injury, they helped one person in front of me before casually putting up a closed sign even though they knew I was stranded (their fault!) and needed help. I ended up spending $1000+ out of pocket to clean up their mess (including the flight to Johannesburg I had to rebook since BA delayed me so much) and haven’t heard a word about reimbursement. I have never had such an awful travel experience in my life. I know delays happen, but they need to take care of their passengers when these things happen, not leave us stranded in a foreign country in the middle of the night with nowhere to go.

The seats are incredibly uncomfortable. My luggage didn't make it on my flight from London to Nashville.

5 days later I have not yet received my luggage so terrible and unacceptable
