It was clean, and the crew did great!

Way off schedule, way to tight of space, no way to sleep being such a late flight! As far as a beverage, they were out of everything!! Nice air line for quick trips,but to fly for 4 hrs at night from leaving at 12;00am, just impossible to sleep or really relax.

They had to fly in 2 plains to try and get us out. They didn’t offer meal vouchers until 51/3 hours into the delay.

Okay 5.3

Boarding was smooth and fast. The travel time was a bit faster than predicted too.

With lack of reclining seats and no complimentary snacks or drinks at all, the comfort scale is lacking. Even the tray tables were replaced by miniature, undersized, pieces. Even with the discounted prices, it’s hard to want to fly with them again.

the embraer 175 is VERY comfortable, despite being a smaller jet.

Just an FYI - the small overhead bin space on the Embraer 175 made it so that many passengers bags needed to be checked at the gate to baggage.

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.
