Airport waiting area was very nice with lots of different seating options. The boarding went very quickly, but that was because the flight was mostly empty. Can't believe how expensive the luggage was. I guess that is why the ticket is less expensive.

The seats were hard and the tray table was almost non-existent.

Price looks great but the service is very bad Fight attendance are good . Plane crew are very helpful and dedicated .

swift flight so that we could get off of the plane quicker.

getting in and out of the seat was awful. especially when the seat in front is reclined. the armrest on the aisle seat should be able to move up as the others in the row did. the metal underneath the armrest is pretty sharp and jagged, scraped my palm as i was trying to get the seatbelt to buckle.

The flight was just fine

The main problem was that when I checked in online, I tried to add on more piece of luggage—for a total of 2 checked in. But the computer ended up totaling it as 3 pieces of luggage. There seemed to be no way to change this online. So I asked them to change it when I got to the airport, but they wouldn’t. What was done couldn’t be changed. Another issue I have is with this review questionnaire. They are questions for rating the food and entertainment which the airlines don’t provide anymore. These should be removed from the survey. They should, however, ask how was the process of making the reservation, check-in, and customer service in general. Both from the airline, and any third party service like kayak or kiwi. I’m not satisfied with kiwi as they were closed when I tried to call them. So I had to just fend for myself and spend money needlessly.

Ticket agents we're respectful

Never received email boarding pass. No kiosks. Charged for boarding pass even though they could see my reservation/confirmation# Website States checked bags15kgs/carry on 7kgs. At check-in stated only 10 klgs total so we had to pay again due to overage. Only water free on flight. I fly every week for work.

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,
