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.

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.

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.

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.

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.
