Pros: nothing really. There were so many rude staff members at this airline. I saw people get yelled at by staff members. They were just trying to get information on the late flights and missed connections. It happened repeatedly. this company has the worst customer service I have seen probably ever.
Cons: They need to care about their customers and care for their customers better. They have a lot to be ashamed of.

We attempt to get accurate prices, however, prices are not guaranteed.
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.
