Fly three, get one free from Southwest

As discussed in [% 2422051 | | a previous blog entry %], Southwest is on an uncharacteristic roll with its frequent flyer promotions.

That roll continues with yet another compelling special offer for Rapid Rewards members, albeit one mostly restricted to travel within the state of California.

Through December 31, Rapid Rewards members will earn one free award ticket after purchasing and completing three Southwest roundtrips within the state of California. In addition to intra-California flights, service between San Francisco and Las Vegas also counts toward earning the bonus. Flights must be booked at southwest.com or swabiz.com to qualify.

So, fly three, get one free.

The only downside to this offer: the bonus may only be earned once.
