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's "All You Can Jet" program -- the $599 all-access monthlong pass to every destination the airline flies to -- goes into effect today. From now through October 8, pass-holders will be gallivanting around the country flaunting their privileges to the rest of the chumps who paid full price for their seats. The $599 pass was so hyped by the media that the total allotment for the passes sold out in record time, and several Facebook and Twitter groups sprung forth to follow the adventures of the lucky few who scored a pass.

JetBlue is quietly reaching for foreign shores with the help of international partner, Lufthansa. The German carrier bought a minority stake (16 percent) in JetBlue about 18 months ago, mostly for financial reasons, and they're now cashing in on the alliance by expanding reach for both companies. Lufthansa will be able to sell seats on JetBlue flights as if they were their own beginning in late September/early October. Conversely, JetBlue will not be able to masquerade as Lufthansa -- instead, passengers will be redirected to the Lufthansa site to purchases seats to any of their 180 destinations worldwide.
