Labor Day has come and gone, taking with it all the white clothes (and shoes) and most of the fanfare of lazy summer days. However, summer isn't officially, officially over until September 21 -- even though Starbucks is already trotting out that damn Pumpkin Spice Latte. In case you didn't get a chance to get away for the long weekend, or in case you did and it was such a blast you need a vacation from your vacation, you're in luck. My favorite trifecta of airlines all launched sales this week, designed to inspire travel lust in those hoping for a last weekend fling, or those ready to plan fall trips already.

JetBlue has its hands full with the pass-holders riding around the country this month, but they've managed to launch an "R&R" sale with flights starting at $29 each way. Long-haul flights are running about $109 each way. Purchase by September 10 for travel through December 16. Southwest has flights for $49 each way through Los Angeles, San Francisco, and San Diego; $94 each way for longer trips. Again, purchase by September 10 for travel through December 17. Virgin America is throwing up deals like $39 each way in California, and $99 each way for cross-country trips. Purchase by September 22 for travel through November 18, December 2-16, and January 6-February 10.
