The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

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.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

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

Amazing KLM service and brilliant economy comfort seats. Well worth the extra.

The seats are too cramped in that plane. If you’re above 1,80m consider alternatives or first class I guess… There were no emergency exits to seat somewhere with more legroom

one of my bags was drenched with fish smelling water and all my new clothes bought at dublin and the 23kg checked in bag were all gone waste with very pungent fish smell and also having stains

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

Boarding in NCL is really bad. I'm sure part of that is a directive from the airport that KLM can't change but part of that is due to KLM policy. NCL doesn't announce the gate of departure until 30 minutes before departure. However, when you arrive at the gate area, the gate agents file everyone into one long line and everyone boards from one line at one time. This line can stretch for 200m...easily. There is a separate line for groups 1 and 2 but you don't know it until you get to the gate area and agents don't announce/advertise it. Everyone else is grouped into one line. Are you in group 3? Doesn't matter...you board with group 5. Traveling with a child? Tough luck...you're stuck at the end of the line and board last. The last part is very annoying because none of the gates at NCL (with the exception of 1 used by Emirates) has a jetway. To board, you must leave the gate area, walk downstairs, walk onto the tarmac and walk up stairs to board the plane. Highly challenging if you're traveling with small children. That boarding process begs for a concession to allow people with children to board first because they will need extra time. But there is no such policy. Just a really horrible boarding experience all around.

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Better attitude training for staff at airport, better training for flight attendants, better food, don’t put us with all the crying babies that cried nonstop for 12 plus hours.

Crew announced boarding started and they asked passengers to form a queue. Actual boarding didn’t start and queue was not moving for around 40-50 mins. Very poor management.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

Crew on this flight was terrible. Especially one practicular female , she was harassing us and other families with children. Flight was good overall, if not her being rude and aggressive

All good. Didn’t get the seats I booked online. Luckily, copassanger cooperated! Mistake- I failed to verify connecting flight seats details at Mumbai. Staff at Mumbai airport to be blamed equally!

My flight was cancelled and I went through hell to get it fixed, with no help from the website I booked it on. My reservation was cancelled AGAIN by the site I booked on without my knowledge a week later. The flight itself that I finally got on was awful. Drunk man belligerent the entire flight, I don't understand how he was allowed on the flight.

Horrible trip. Plane was late , so late . the flight conditions were very uncomfortable.

Pros: "Quick Check in"
Cons: "The crew were not nice. They dont even pick up garbage during the 9 hour flight. They give you a gallon of water in a huge bottle without a glass and you are on your own."
Cons: "The TVs didn’t work even thought the steward ESS restarted them ."
Cons: "Everything is good! But the monitor on back not working very well lot of brakes when you watch a movie or listen music!"
Pros: "Nothing to like"
Cons: "This Iwa’s very bad experience. Never again will use LOT"
Cons: "The worse experience ever. I booked the flight and then they canceled it, i tried changing the dates but the website was giving me an error so i called them, after being on the phone for 2 hr some guy answered who seemed very tired and not thrilled working for LOT. Rood and not helpful, told me to try FB messenger and online changing again. Failed to get a voucher, refund or change the dates online, was still getting an error. on messenger they answered and told me i can get a voucher, i told them i don't want it and after that they stopped replying all together. good thing i got my money back by filing a dispute with my credit cart company."
Pros: "The crew was very profesional . Our fly was safe and on time."
Cons: "Maybe variety of good movie could be better ."
Pros: "The crew was really great, seats like in any Airbus (I guess better then Boeing)"
Cons: "Very old movies as entertainment."

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Our flight to Chicago O'Hare was delayed an hour, causing us to miss our connection to MSP and spend an extra 3 hours at O'Hare so we could board a plane with a damaged door and wait another 45 minutes or so. The crew was great, the food decent, The drinks were great: 2 glasses of a nice South African Shiraz, an ice cold can of Beck's Beer, and Dewar's White Label on the rocks.

A350 has great entertainment. Make sure to watch the plane's external tail and nose camera's on landing and take off. Seats were a little hard for a 10 hour flight. I am gluten intolerant, they had good alternative meals for me on the flight.

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

Need more time for connecting flights in Munich Food seems worse now on Lufthansa Very uncomfortable seats

Better flight than mum to Frankfurt. But food was very mediocre.

Flight landed on time but land services kept us in the plane for 3 hours. I missed connecting flight.

Rude staff and seats are only can accommodate small people. If you 6 feet and up be ready for struggle.

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.
