The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!

Flight crew was good, we arrived early on flight out and back! Feel like seats are tinier than ever, maybe it was just me. Food (water & pretzels) were OK, but nothing special (then again it was a short flight, so I didn't expect anything). Plane was small so we needed to gate check bags and the gate attendant came around and tagged everyone's bag for us, well before boarding which was hugely efficient - kudos to her on that!

Gate attendant's mic was broken (or she didn't know how to use) so she had to yell into the boarding area.

The gentleman at the gate was super helpful and helped us check our bags at the gate.

Zero leg room. Zero arm room. The entertainment system did not function. No food for such a long flight unless you pay more then the food is actually worth.

We flew for only 45 minutes on a flight that had been scheduled for 1.3 hours.

The long delay seemed strange, as the plane had arrived from Costa Rica. Why would an airline schedule the same plane for an international flight and then a short hop from Newark to DC without adequate time in between? The departure gate at Newark was absolute chaos! Announcements were overlapping and not understandable. There was inadequate seating.

YYC is a nice airport. I have found I like Canadian's more then Americans when it come to air travel.

LAX is not a convenient airport at all.

The actual flight was fine. But leading up to it not so much.

Please inform travelers that their passport must not expire within 3-6 months of their trip to France. I was unaware of this and was not allowed on our flight in Philadelphia because my passport would expire in two months. We lost an entire day in France because I had to go to the customs office the next morning and get an emergency passport. I travel frequently, but somehow was not aware of this rule. If I had known I would have fixed the issue months ago. Multiple people viewed my ticket and passport before arriving in Philadelphia and no one caught this error until right as I was boarding the flight to Paris.

Best fligh I had in some time. Left on time, arrived early very attentitive crew (with smiles as they worked through the rear cabin - wish I had their names to give recognition for/to). Food rating should have had a ‘NA’ as I nor partner did not consume any food.

Can’t think of one thing - unless a flying saucer could have delivered me like in about 5 minutes to Cabo! Ok - maybe one thing: charging for a checked bag on international flight seems rediculous (you asked).

The flight itself was fine

I bought the tickets together, but was informed at the ticket counter that i had only purchased tickets—not boarding passes. Boarding passes needed to be purchased by paying extra if my husband and I wanted to sit next to each other. I tried calling the customer service line through kayak and waited on hold for a long time with no indication of wait time. When the gate agent arrived, we asked and were moved to seats next to each other right away. The ticket agent at initial check in was very abrasive and non-solution oriented. if what she was saying was true— that we only paid for tickets and had to pay extra for boarding passes together— that was never made clear during the booking process. It’s unlikely I’ll use kayak again unless I know for sure what I’m buying.

seat and seating was nice, boarding was efficient, movies okay

while the dinner was okay, the stromboli which came as a snack of sorts was terrible and caused me to be "on the run" for the next 12 hours. the last five hours of the flight and then at home were awful

The flight was good, as well as the attentive staff

Kayak messed up royally by saying this flight was an Iberian. We went to the Iberian terminal as the email I received said the flight was an Iberian. After waiting on line for twenty minutes we were informed that this changed to an American Airlines/ British airways flight. We had to AirTran to the next terminal and almost missed the flight. Kayak needs to keep their customers better informed.

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.

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.
