Plane was on time. Boarding was seamless. Crew was very polite and attentive. I even had two coffees with hazelnut creamer. I love southwest and how they continue to offer amenities at no additional fee!

The plane was completely full and it was comfortable. The flight attendants were friendly and always had a smile. Very professional.

One of the flight attendants wanted to be a stand up Comedian. It was a little trying but my wife liked his routine more than I did.

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.

Crew was great

Flight delayed slightly, not too bad, but it seemed to take a long time to get the plane boarded, which is unusual from my experience with Southwest

Bossy lead flight attendant and the mid-cabin was very cold and not corrected even when a number of people asked.

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.
