Imagine, for an entire year, you could buy a plane ticket and a companion of your choosing can fly with you for free.

For California residents only, that dream can become a reality if you fly Southwest Airlines.

Here's the deal:

If you live in California and sign up for a Chase Southwest Rapid Rewards credit card, you also get a Southwest Companion Pass after your first purchase -- meaning a friend can fly free with you for a year. You can also change your so-called companion three times.

Also, there are no blackout dates or seat restrictions.

However, the deal won't last forever. California residents have until Nov. 30 of this year to take advantage of this offer.
