The crew personnel aboard the plane was friendly and the seats confortable.

They made me pay $45 for a 16 inches carry on back that I have as my only luggage , because according to the counter employee, my handbag (purse) was too big so it was considered as a second carry on. I requested a waiver, because I’m an Army Veteran, a senior citizen, but it was denied by the counter employee.

Not a thing.

Everything. Worst service, constant delaying for flight, long wait when boarding. I haven’t seen such a bad airlines before. The seats were horrible, the pull out tables are so small. The customer service over the phone didn’t help what so ever. Took them over 10 minutes in for myself to just ask them to look up my ticket and actually do something about the issue, online booking messed up my name on my ticket and almost cost me $2000 to change it.

Everything is good except our lunch as described below.

They ran out of chicken breast in our lunch packages, so the stewardess went back to get it. After 10 minutes she still did not show up, we turned on the help light, and still no one came. Finally she passed by and we reminded her the 2 chicken breast lunch packs, she said : "Sorry, I've forgotten about them" and ran back to get them for us.

Corn nuts for snack. I'm allergic to corn. I get people want snacks on a flight and you can't make everyone happy. It was ok. I just said no to them.

The crew was so warm and kind. The really made the trip.

I fly often. Mostly internationally for work, but often enough domestically that I am a learned flyer. I hated that there was no complimentary anything on this airline. When checking in, I had to pay for my seat, after paying the stated price on this site (btwn 13-45 $). There was food and beverage, that you also had to pay for, no complimentary soda or nuts on this airline. Also there was a carry on baggage fee!!!! Like wtf. Overall, though the crew was great, I would NEVER fly this airline again.

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.
