To celebrate their 3 millionth Facebook fan, Southwest is doing a 50% off sale today for travel on specific dates.

Must book today (8/3) for travel on 9/5, 9/11, 9/18, 9/25, 10/2, 10/31, or 11/6.

Sounds like it doesn't include every destination, but for kicks I tried LGA-ONT and got a $193 round-trip fare including tax.

Use coupon code LUV2LIKE
