Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

no issues at all... Kudos to the food. This time was really really good

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

Mostly fine. Minor delays departing and arriving. Quite a cramped plane, not so much as regards legroom but very narrow seats. Quiet nice food. Non-working USB charger. Flight attendants were helpful but not particularly proactive — one had to work to get their attention (but all was fine once they notice you), very Dutch style:)

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

Well, in my case; the flight was delayed 1 hour, we have to wait in the plane to get green light. And the plane (probably because was a short trip) did not have entertainment or WiFi. No a good experience.

I arrived 59 minutes before the flight in Tampa due to Massive traffic jam and the flight was closed and I was told that I’d simply have to “book a new ticket on line myself and the gate agents couldn’t help me”. Even though the flight was delayed over 30 minutes, (leaving one hour and 29 minutes before departure, they refused to assist in any way explaining that it’s automatic and there can be no exceptions. Horrible experience due to poor management at gate. I fly this option 2-3 times a year and have a good experience with the cabin crew etc. But, Tampa agents are not trained or allowed customer service. I once was a gate agent for USAir, I know times have changed, but forcing me to purchase a new ticket and complete indifference and inconvenience. No thanks

Crew members were good. Seats were packed and too tight .

Carry on luggage size for economy passengers significantly smaller than other airlines, so nearly all ecomy passengers had their bags taken and checked.

Had a short layover in Zurich, luggage marked expedite and short layover but still didn’t get luggage when arrived in Split until 3 days later even though husband got his.

On time flight, I requested wheelchair in Zurich , when I arrived they were no where to be found, I had one hour between flights I had to walk with great difficulty.

We had issues with upgrading our seats. The flight itself was fine.

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

SO disappointing. I spent so much money on this ticket, for them to cancel and not be able to rebook me in time. They were very unhelpful, and condescending throughout the whole Swiss airport. Will not be flying again.

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Overnight flight in the old style Business class, but still very good.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

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

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

They canceled our flight last minute and we had to get another flight with twice the cost

Dinner was excellent - beef stew, the eggs for breakfast were only ok. It was soooo nice that there were so many options for movies and games.

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Boston Logan is a crummy airport - signage is terrible or lacking in areas. Boarding seemed to be a free for all and with all the different airlines speaking, you couldn't tell who was supposed to be where and when. Plain and simple, airlines should board from the back of the plane to the front. Also someone was sitting in my seat. By the time that was figured out, I had to place my overhead behind me which made de-planing more difficult. Logan is not Lufthansa's fault so that is not on them, Boarding is on them! Still, overall it was a Good Experience flying with Lufthansa. This is not my first flight with them...

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

The flight was provided by Aer Lingus and our seats were in a poor condition (15A & 15C). They looked like they needed repairing/replacing and were uncomfortable for such a long flight. Also the arm rests on Aer Lingus planes do not lift more than around 45 degrees, instead of the usual 90 degrees upright, meaning you cannot maximum the space between you & your travel companion so as to be more comfortable for such a long flight.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Delay, lost vacation time and travel time now more than 24h

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

Very bed boarding, there was overbooked and make a lot of problems and noises

There was a problem in the luggage because there were not porters

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.
