Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

In never flown this flight, because my flight coning from Barcelona was delayed.

I did not have a good experience in both flights of Etihad. First of all, when I was booking the flight, there were two options. The first option was a cheaper flight with longer layover (9 hrs), or a more expensive flight with shorter layover (2 hrs). I booked the expensive flight with shorter layover because I wanted a more comfortable trip. A few days before the trip, Etihad informed me that the departure time of my first flight will change 7 hours earlier, leading to an 9 hour layover, without giving me another option nor reimbursing me for the extra cost. They didn’t even send me an apologetic email for this change. Regarding the flight experience, I would rate it as mediocre. This is mostly because the pilots of both flights did their best to give us the worst approach to airports that I have ever experienced. In the case of the first flight they had to aboard the landing and took off again right before touching the landing strip. The captain said that it was due to wind conditions but the second time the pilot followed the same direction as the first time to land the plane.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

Lost Baggage - very frustrated…learned that bag was never put on plane.

I think it’s time that somebody set a standard for the temperature in the cabins. I would rather it be colder than anybody that wants to have a blanket have a blanket to keep it so warm at times is unbearable and quite uncomfortable. That’s the only thing I would add.

For the price we paid, I couldn’t complain. Was good value for money. Service was excellent but food was mediocre. Crew were excellent and spoke English. You will never go hungry. The food was ample but was mediocre. Entertainment limited and wifi doesn’t all allow you to access some social media. The best part was comfortable seats and bed (business class) with a screen to close out the rest of the cabin.

The boarding process was really slow. The air crew was amazing. Also the food options and the entertainment on board.

Delayed over 2 hours. Bring your own snacks or prepare to pay. No entertainment and no plug plugs for charging.

The flight was delayed but I was still able to board the connecting flight in Munich.

It’s not bad, simply it’s not as it used to be years ago.

SAL to FRA - Original flight was cancelled less than 10 hours before scheduled. Did receive lodging at no cost for 1 night. Coordination between Lufstansa and hotel was very poor and we had to pay for a meal we thought was to be paid for. Traveling from SAT to Denver coordination between Lufstansa and United was very poor and we paid double for our check-in baggage. We are hoping to that refunded. We wish other airlines would fly to Salzburg as we plan to visit more often.

It was a good flight overall, I just hate it when we get delayed because there is a small amount of layover time in Munich and you have to actually run to the next gate.

I asked for antibacterial wipes three times and each time I was told they will bring it to me right away with nothing delivered. I finally went to the galley and was told you did not have it. In a post COVID world that is just wrong. The crew was very non compassionate to passengers asking basic questions about food. Very disappointing and makes me reconsider my routing for the future trips.

I like entertainment on the plane once I got it to work. The touch screen really had a hard time responding to touch. Boarding was excruciatingly slow. Getting through passport control was bad enough but security had a line of us not moving at all while this team of security people took their time going through every item of one single passenger, not letting anybody else advance (only one lane open while the equipment was there for 2). I would have missed my connecting flight had it not been an hour late itself. I know the airport is not the responsibility of Lufthansa or Kayak but I mention it as the reason my experience was not great.

My connecting flight was cancelled then delayed for four and a half hours with a €20 voucher for my trouble. I think that is an awful apology because the next flight they put me on was horrible. It was overbooked, the flight attendants were of absolutely zero assistance (embarrassing actually) and the transportation shuttle to the plane was as hot as a sauna. Terrible!

Still haven’t finished the flight. Day 2. Missed flight connection for reasons not explained and had to spend night at hotel. Booked on early flight next morning and had to deplane for technical issue. So tired. Not happy. Seat changed to ver back of plane like they did on the outgoing flight. This airline is second rate at best. Bad form. Never again. Not duly compensated

An hour to check-in because they were not organizing the counter personnel well; they lost my baggage and after 48 hours they so not pick the phone, answer emails, and I still do not know how to claim my essentials (its purposely not their on their "help" page).

Much better than from Singapore to London, which was awful. London to ORD was business class experience expected. Friendly and helpful flight attendants, decent main course, delicious dessert, comfortable lay flat private seats.

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.

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.

One if not the best Airline I have traveled so far. My only complaint is that flights where delayed.

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

One particular crew member wasn't helpful in the cabin .

Check in staff were rude and argumentative with most passengers. Overly scrutinizing with baggage allowance. Delayed, again. Becoming the norm with BA.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.
