They came around often to see if we needed water or anything. Food was good.

It was way to hot on the plane, I actually couldn't even sleep because I was sweating so much. They give out blankets so I would think it would skew to the cool side so people can adjust themselves. Nothing you can do when it is too hot other than suffer.

Attentive and polite staff. Comfortable planes. On time flights.

I accidentally left an external battery in my check in bag and they stopped me to open my bag and remove it as I was boarding. This is obviously my fault but I wish they had called me up earlier to not disrupt the other passagers and slow the boarding process.

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.
