Southwest Airlines currently has 50% off all flights to/from Seattle. Which can make some deals downright a steal. Southern California or Vegas from about $65/each way, Bay Area for about $47/each way (with taxes that comes to just $115 round trip). Or to the East Coast (D.C. rated in at about $211/RT all-in). As noted on the website, book by 11:59pm PST today for travel through May 31st.
Amazingly enough, there are actually some other airlines deals which are already even better than the 50% that Southwest is offering. Seattle-Birmingham as low as $135, Orlando around $200, or anywhere else you care to travel is downright cheap through April. This is the time to go somewhere.
Now I just need to figure out where I want to go.
