This airline is disaster. They trielt live on the planet don’t give a &$!@ Made us buy new tickets for the following day for a type o on the ticket. They just didn’t care...

They kept me and my two year old in the plane for almost 4 hours and told us that we will take off every ten minutes, but obviously we never did. We got rebooked for the following day. They provided a small room to stay in and $7 wach for food. They treated us like a huge inconvenience. We had to pay for food, my husband had to take another day off work to come get us. This airline is shameless. We are spending more money to with a different air line next time.

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

The flight actually left.

Poor communication. Flight originally at 11:35, then 12:05, then 12:15... At 11:55, they said they would start boarding in 20 min. How can you do that and still take off at 12:15? Answer: you can't. Just be honest and keep us informed. Bonus: United sent me an email saying that connection had already left (it hadn't - thanks United! - awesome service as always!)

una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen.

Ground staff at Manchester very helpful

Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros.

Awoke next day and called airline to confirm, they stated my refund had been processed, I would not be on the flight, and there was nothing that they could do for me.

12 of January, 2018 Dear Austrian Airlines authority, I address to your kind attention to asist me to get to me the hat qhich I lost on board of the flight 1576 when I arrived to Vienna airport on my way frpom JFK to Lwo. It happened because it was no room above my seat's bin and the steard helped me to get my heat in another bin. Unfortunately I forgot at the moment when I left the board of the plane, a minute later I reminded that I forgot my hat but I was not allowed to go back and get my hat. I tried to communicate with the Lot&Found office in Vienna airport as I had 2h40 minutes in connection time and it was enough time to get me back the hat, unfortunately nothing was really done from the airport staff to get me my hat and made to me possible continue traveling with my hat. I spoke to two managers, the name I could share with you if you need. The Found office registered my black hat and the plastic box under the number F2018/000682. In this situation I ask your offices to deliver my hat and the plastic box to Lviv airport as sson as possible as this is a special hat for my daily prayers. I wish you best and ask for your kind assistance to send the item as soon as possible with the nearest flight. Sincerely, Meylakh Sheykhet

The extra $50 seats were roomy.

Flight was delayed and no one knew why!... Plane had been sitting ready at the airport for hours. Novice flight attendants, they each picked on different things others missed just before them. No consistency, seats left reclined during takeoff and landing for example. One way there was drink service once even though it was a smooth flight and the return had drink service twice even though it was bumpier! Entertainment does NOT work on androids, it is NOT the AirCanada app they tell you to download prior to the flight, it's an AirCanadaRouge.pk file that needs to be downloaded in flight! Which means we're stuck paying for the iPad and of course only with cc because there's no wifi for debit cards.... AC needs to stop this insanely mediocre and yet expensive monopoly.

Flight was 2 hours late, causing a missed flight. Baggage took 90 minutes to arrive. The airline provided no info on connections as hundreds of passengers stood around for an hour and then chaos reigned as all rushed to get rebooked in only two lines. Nobody got rebooked until the next day and had to stay overnight in hotels with a voucher that provided only minimal food after a 15 minute walk to a fast food restaurant. the following day we were rebooked to Copenhagen rather than Berlin, with no guarantee of a connecting flight. I was forced to buy another ticket on another carrier in order to make my own wedding.

Nothing

Worst customer service experience of my life - they cancelled the flight only for people with connections and booked me to a week later.

There was no rebooking to Berlin. WOW offered a flight to Copenhagen with no guarantee of a connection to Berlin.

Food was reasonably priced. Price of flight was great.

Not a lot of room. Tight space.

Flight cancelled due to overbooking, notification received while I was en route to the airport. Was assured I would be on the flight for the following day. Awoke next day and called airline to confirm, they stated my refund had been processed, I would not be on the flight, and there was nothing that they could do for me. I was forced to rent a car and take a completely different flight from another airport at a much higher price. Never again.

Flight was 2 hours late, causing a missed flight. Baggage took 90 minutes to arrive. The airline provided no info on connections as hundreds of passengers stood around for an hour and then chaos reigned as all rushed to get rebooked in only two lines. Nobody got rebooked until the next day and had to stay overnight in hotels with a voucher that provided only minimal food after a 15 minute walk to a fast food restaurant. the following day we were rebooked to Copenhagen rather than Berlin, with no guarantee of a connecting flight. I was forced to buy another ticket on another carrier in order to make my own wedding.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
