The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.

The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.

Didn’t fly KLM because they cancelled our flight August 31st. Delta was our airline on. Direct flight from Frankfurt to Detroit. Departed early, arrived earlier than expected.

an he late. super rude gate agent, to every person. spoke down at people.

The internet that was free was terrible, the turbulence was pretty bad - uncontrollable I know.

My business class seat was inoperable and unable to recline for 10 hour flight.

It was good. The leg room was not great in Row 1.

The crew was very kind and always smiling. The seats were great and I was very comfortable during the flight. The only thing I didn't like was that the lavatories got really dirty at some point during the flight. Other than that my experience was great

Crew was very helpful with mobility assistance from end to end. Very caring.

When we checked in my friend and I were sitting seperate. By the time we got to boarding, they automatically switched our seats. I really liked that.

I trust Delta. I travel comfortable. The snacks could improve or could go to something as a little sandwich.

The counter person at the gate was rude and demeaning, to the point that I wouldn't fly this airline again.

In Barcelona had to descend from the aircraft down the steps with heavy bags, and then get on a crowded bus to the terminal

Not the greatest. The staff was unpleasant and we had delays. The boarding was done out of order.

ok, butt flght was delyed for 2,5h from Frankfurt, and next Flight to Columbuse same

Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

Boarding was conducted in a confusing manner as no boarding group was displayed on my boarding pass and group calls were inaudible. Flight was delayed due to oil issues and loading issues. Had to wait almost 45 minutes for bags at baggage claim.

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

For my wife to be seated with our two children they put them in the last row on the plane where the seats don’t recline very much. The seats in front of them reclined fully which is basically in the lap of the last row which made it difficult to eat, move or watch the entertainment provided.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

To many flight at the same hour...no respect to handicap....

The seatbelt light was on the whole trip - inconvenient but also unsafe. I was told to keep the window blind down the whole trip though I specifically paid for a window seat to be able to....see out the window. It was also two hours late causing me to miss my connection.

There was a big delay and I missed my connection flight

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

The plane was broken so we had to change planes.

The new seating in BC was a joy. My vegetarian pasta dish was excellent, very creative. The chicken potpie was ..... The crew was extremely focused and impersonal, but everything worked.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

On time! Cabin crew attentive. Good WiFi sofrtvterm free internet appreciated

Iberia didn’t let me check in online or select my seats, the experience overall was not very pleasant

It was a smooth trip, everything ok. The crew were so nice and professionals. The only thing that I didn't like was the tiny dinner table of the plane but I guess it's not the crew fault. Overall I recomend flying Iberia.

Everything was on time and easy. Food in business class was great. There was no entertainment on board, though with business class you could get free internet, but so spotty it wasn't worthwhile.

They could have provided more than a premade mass produced tina sandwich for a 10 hour delay and/or had something available on oars other than potat chips once we boarded. They also could have not lost our luggage. Or barring that, at least foled a claim for us once we landed. Instead all of those things happened and they told us if we wanted to file a claim to do so online. I laid for business class for both of us. What an incredible waste of money.

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.

This is where i leave an airline review. Test test test!

business class food was pretty average otherwise it was a good experience

okay, will recommend from PR to Madrid, faster turn around

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

All went smoothly, no problems; friendly crew. I would have appreciated a head pillow ;)

Never made this flight it was unconfirmed by Iberia according to American Airlines This trip was a total nightmare, got to the airport in Wed March 8th after confirming all flights, only to be told by American Airlines that we are not confirmed on the flight. We met a pretty rude and unhelpful AA check in agent by the name of Ali. American said it was not their problem, contact Kayak/Chatdeal and sort out your issue.Chatdeal said all flights were confirmed and it is the airlines fault. So it went, we were kicked between American, Kayak and Iberia spending hrs on the phone- all said it is not their fault.Spent 9 hrs in the airport on Wed 15th trying to sort out. Luckily, we met a really nice AA agent Shawnna G who went way beyond the call of.duty to help us out. We were put the next day on Thurs 16th from DfW to San Paulo Brazil the onto Madrid!! Imagine that..10000 miles and 20hrs of travelling to get to Madrid from Dallas!! Our trip took 3 days to get there ..Wed 8th Thurs 9th and Fri 10th.Got there on Sat 11th, so lost 2 days of our vacation and a lot of emotional and physical stress on our 2 kids travelling with us.

I was disappointed that paying nearly $5000 more for business class for two didn’t really get me any more than a larger seat which as the last row in cabin reclined only mildly and the foot supports were of minimal help and left no room under seat ahead for carton bag. Second, our checked luggage was lost and took us two long days and we’ll after midnight each of them and multiple calls and 30 euro trip to airport in person to finally get them. Would you do this again?

I bought premium economy tickets with a fully flexible fare, and made seats selection for me and my son: window and aisle. After checking in online, Lufthansa cancelled the seat assignment without informing me. As a result, my son and I were assigned mid-center row seats, in different rows. This ruined the trip.

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

Way too crampled. Charge more and put in less seats.

I was first assigned a seat that could not recline fully and was at the back of the craft. I was not able to select another seat during check-in even when opting to pay for selecting a different seat. I had to contact the airline and spent 25min with a chatbot and was then transferred to an agent who was very helpful and could change my seat (free of charge). The entire process took me one hour. If I happened to not have that hour available this would have been a problem. And that was only to check in. The next problem is that the airport lounge I had access to is located landside. How strange. So it means that you need to allow time for security check and passport control and boarding time when leaving the lounge, which makes it almost pointless having lounge access unless you have a very long layover or arrive 5 hours before the flight. Inflight service was okay. But not up to par with the likes of QA, SQ or CX, even though the price is the same or even more. It was much better than the domestic flight where Lufthansa is actually a low-cost airline with legacy airline prices.

One of the best airliner in the world But airport was very poor

Very bad 3 times change the gate and too much delay...

the blanket was great and pillow helped. really need a toothpick packed with meals

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.
