I don't know how airlines get away with all the stipulations and regualations they have in the buying process there is. Otho g I like about the scam artist they are

The fact they they can just make it a policy and then because the employees have to have a job and enforce it blows my mind. 200 dollar transfer fee plus the difference in the ticket when it's over two weeks in advance. You people are scam artist

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.

I liked having the built in screen on the a321. Americans streaming service has lots to offer but the built in screens have more choices. I get why they want to just offer the streaming but I appreciate all the choices! There was a group number enforcer at the gate to make boarding more organized! She was polite but told the mobs that try to use the premium line to wait their turn.

I asked for upgrades to and from Chicago. I’m a gold member and fly for leisure fairly often. There are so many people looking for an upgrade these days that you’re rarely getting the opportunity

The crew was lovely. Really nice, and did a wonderful job with the cart service.

We ended up being deleyed about 30 minutes, in damp weather. It's not like it was snowing. Not sure why it took so long. B/c of baggage charges now everyone brings a carry on. This seems to slow the process of boarding as know passengers are asked multiple times to check baggage (for free, which is the one nice thing) before boarding b/c the overheads will be too full. Group 6 which I was in seemed like it was just the rest of the plane. Super busy, took me forever to get to my seat all the way in the back. Why don't airlines reverse board? People sitting in the back should board first. I feel like this would save so much time.

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,
