It looks like we're starting to inch through spring and toward summer. The new Southwest and AirTran promotion will last until midnight Thursday for travel from March 6 through June 6 and only on Tuesdays and Wednesdays for domestic routes. A 10-day advance purchase is required. Here are the terms at Southwest and at AirTran.
Last week JetBlue launched a one-day promotion for Tuesday-Wednesday flights through April 3. Southwest tends to be first out of the gate in terms of promotions to fill seats for new seasons and this new one, with its Tuesday-Wednesday sale-seat terms and early June endpoint, likely marks the start of a few more such short-term offers in the industry to wrap up spring -- a generally slack period (with spring break exceptions) for leisure travel.
UPDATE 10:38 A.M.: JetBlue has just announced a one-day spring sale for 20 percent off fares on flights from May 1-June 12. Here's the website with the other restrictions. To get the fares you will need to use the promo code: SPRING12If you are planning summer travel, early forecasts suggest that seats will be tight and expensive, given that oil is once again on the rise and airlines have really tightened down schedules. It's a bit early now to shop -- carriers start aggressively managing seats about 10 to 12 weeks out. But it is time to start casually looking around. We should start to see summer deals in March.
