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

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

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.

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.

At the transit could be less time not like 12 hour 6 hours the mix should be 4 hour, thanks

Pros: "Crew was great, on time flight, clean plane."
Cons: "Entertainments options were shockingly few. Honestly have not been on a plane recently with so few and limited options of TV series and movies. I was extremely surprised. Wish I had know and I would’ve had more options for my family."
Pros: "Friendly crew, great access to a variety refreshments, robust entertainment library."
Cons: "No suggestions."

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 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.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

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.

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...

Overall, the flight was comfortable without any serious issues. Transit through Frankfurt airport was a little confusing, but not too difficult if you follow the signs

There was a screaming child behind our seats. This prevented us from getting any sleep during the night.

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

Staff disappeared after dinner service until breakfast, no help with beds, no help running to our gate to catch connection cause flight was late, our luggage didn’t make it, took over 24 hours to get luggage to hotel, no compensation!!

Everything was good except food. I believe there is room for improvement

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

my flight was at 3:45 after that they delayed to 4:40 I have transit from Chicago to Frankfurt and Frankfurt to vina airport from vina to Erbil buy the Time I come to Frankfort my other flight left me I have to stay at airport all day with my 5 kids ask for help no one help me I spent at airport almost $450 just for food was horrible flight ever I call and ask for hotel from united customer service they been telling me we can’t provide any hotel I need some refund or fixed my flight when I return to America need some one respond my email

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.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.

Leg space was not enough. The meal was not satisfactory.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.

The entire process was flawless and as expected flying first class. The only thing that I have a complaint on...when first boarding, the plane was EXTREMELY cold; then when we were trying to sleep, it was way too hot - just better regulating (especially trying to sleep) would have made it perfect.
