According to mashable.com, on August 3, Southwest Airlines has offered half-off fall flights only on the date mentioned to celebrate the growth of its Facebook fanbase to 3 million.
The offer applies to select roundtrip flights (they’re labelled “Wanna Get Away”) that fall on Sept. 5, Sept. 11, Sept. 18, Sept. 25, Oct. 2, Oct. 31 and Nov. 6. Fans are asked to use the promo code “LUV2LIKE” when booking on southwest.com to take advantage of the offer, which expires at midnight PT on Friday.
Southwest wasn’t able to tell me what percentage of its flights qualify for the promotion on each of those days, but I was able to find at least one flight from New York’s LaGuardia Airport to my home airport in Orange County, CA, and back on each. It’s possible to get a partial discount by only booking the initial or return flight of your trip with the discount. Unfortunately, those who have already booked flights on those dates will be unable to take advantage of the offer unless they cancel their previous reservations and make a new one.
