On a 16 hour journey, we only had 2 meals and no snacks. I usually fly Lufthansa. They provide 2 meals and a third snack (usually a pizza) and keep additional snacks and drinks fully stocked in the back of the plane. None of that existed on this flight. The crew was very uninterested. Seemed very absent and not into assisting patrons. Overall, not what I have experienced on prior Qatar Airways flights. To add insult to injury, I was sitting next to an EXTREMELY smelly person, which didn't make the experience any easier :( Not the airlines responsibility to ensure patrons exercise proper hygiene, but that didn't help the situation with my hungry growling stomach.

From Joburg to Doha, the plane was clean and the food was good. . From Doha to Washington, not so much. I went to 3 bathrooms and all the sinks were stopped up.

The food from Doha to Washington was beyond awful!!! I wud scrap that whole menu PLEASE. I WAS SEVERELY DISAPPINTED. The previous Quatar flight, the food was different and very good. Please check on this. Also, the sinks were stopped up. Gross.

Punctual, great food in Premium Economy, friendly crew.

Took over 75 minutes (after arrival) for baggage to arrive on the carousel. Boarding area did not have well-defined lanes for different groups.

The airlines didn’t even notify the passengers with the connecting flight. As the arrival was little late, all the passengers have missed their connection flights in Toronto and there was no notification or communication made on the new flight. When I went to the Air France counter in the airport, the staff has gone for the day and trying to get a hold of telephone rep took 2-3 hours and I by the time I found about my new connection, I was already late. Somehow I managed to get to the Terminal 1 and when I spoke to the lady (indian) at the Check-In counter, she has refused me to Check-In because i slipped the line up. The people in the lineup didn’t have any objection and they let me go first for Check-In as I’m already late to my flight. I wante to say something to her, but I’ve controlled my frustration. Luckily the other person in the Check-In counter offered to help me Check-In. Here is my word to the Indian lady staff “F**k You B***h” - learn some people skills.

Although we departed late from Paris, it arrived on time to Mexico City. Most of the stewardess very professional and kind.

Although we traveled in Business, all business cabins were full of children, tired crying, walking around. My suggestion to AIR France would be that the small cabin of business were assigned to adults only. Regarding food, some options were not available when our turn came.

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

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.

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,
