They moved us from the gate to have an "on-time" departure even though we sat on the taxi way for a while. Why do airlines do this? Are on time stats more important than customer comfort and satisfaction. Then they kept the lights on during the entire flight to "sell" their products. Please, give us at least a free glass of water. You are only cheaper than other airlines when you get a $9 fare, which you have to pay to have anyhow. So they are a bare bone airline, but charges are for everything. This airline stinks, I will not be flying them again unless I absolutely have to. I thought United was bad, but they are great compared to Spirit.

Excellent Crew - I flew standby, so have great gate agents and flight attendants makes all the difference when you’re hoping for a seat. In flight they are professional and personable and keep you up to date on what you need to know! Plus, I’m always happy when my flights have USB ports so I’m fully charged when I deplane.

I always want more leg room or a little more room under the seat in front of me. But I didn’t upgrade for a roomier seat and there was more than enough overhead space, so truly can’t complain about it!

Overall it was another positive experience and great value.

Flight attendant told me I couldn’t sit in the exit row because I chose to wear a seatbelt extension. Is this a new rule? I’ve sat there many times without an issue. I can perform all the functions needed to open the exit hatch and help people escape. Why does being a little more comfortable mean I can’t sit there? The seat belt comes off the same way. What am I missing? I moved without questioning her but the rule, if there is one, makes no sence.

You don't have to pay extra to check a bag.

Due to Southwest's policy you don't get a seat assigned, so its not great if you are traveling with someone. My boyfriend and I did not get to sit together.

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.
