Not much.

Where do I start. Ticket counter at check in is an abomination even if you did it online as they suggest. The airline groups together those needing check in and those dropping off bags which makes no sense at all. Results in a long process. Nickel and dime you until the savings from a traditional airline is non-existent. Seats are uncomfortable, crew is unpleasant. No wifi or entertainment. And baggage is always delayed. Pay the money for a regular airline.

I like that two checked in bags are included in the price. ISP is close to my home and easy to get in and out of. The airline is always on time, even when there is a late departure.

The seats have changed. They are narrower in width, the knee room is less, the staff while still professional is more serious, not as fun and friendly. Spicy snacks and peanuts are limited. Cookies go better with tea and coffee on the late night flights.

The flight had no pilot assigned to the flight yet the attendants still boarded us. Then we waited on the plane for an hour before exiting the plane. The attendants gave us little information on flight alternatives and when the flight was finally allowed to board again, they did not announce it and so had I not been waiting close by, I would have missed my flight. It was extremely disappointing but not shocking with all the scandals that have occurred this year with American Airlines. I do not recommend flying with them.

Escape row seat in a non-escape row wasn’t too fun or comfy. Took half the flight to connect to the WiFi to watch movies to discover that the selection was limited and poor selections at that.

Hi. I was shocked that there was no food served on the 6 hour flight from Boston to LA. And the seats are way too small. I’m not large and I felt like I couldn’t breathe. There wasn’t enough help, either.

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.
