My flights were so behind I missed my connection for Toronto to Tel Aviv and was rerouted to London and then Frankfurt but the plane was late getting there as well. Air canada had no crew on the ground and over and hour wait for customer service on the phone so i had no way to find out what my reticketing status was. I was passed off to numerous other airlines and sent through the airport to the incorrect terminals in heathrow causing another missed flight. Air canada did not accept the responsibility to maintain my reservation and get me to my destination efficiently. Even when I spoke with a phone representative the person was rude and never sent confirmation of my flights so I had no reference point for flight numbers or air lines. All of his added up to more than 13 hours of delays on what was already a 24 hour trip. Worst travel experience of my life.

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.

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!

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!)

Mediocre 2.0

My flights were so behind I missed my connection for Toronto to Tel Aviv and was rerouted to London and then Frankfurt but the plane was late getting there as well. Air canada had no crew on the ground and over and hour wait for customer service on the phone so i had no way to find out what my reticketing status was. I was passed off to numerous other airlines and sent through the airport to the incorrect terminals in heathrow causing another missed flight. Air canada did not accept the responsibility to maintain my reservation and get me to my destination efficiently. Even when I spoke with a phone representative the person was rude and never sent confirmation of my flights so I had no reference point for flight numbers or air lines. All of his added up to more than 13 hours of delays on what was already a 24 hour trip. Worst travel experience of my life.

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.
