Southwest announces late summer, fall fare sale

Southwest Airlines Co. has kicked off a three-day air fare sale.

Southwest on Tuesday announced the sale with fares starting at $49 one way to select destinations from Aug. 25 through Dec. 17.

Blackout dates include Sept. 1, plus Nov. 21 through Dec. 2. Other restrictions may apply and seats are limited.

Some sale flights are on AirTran Airways, which Dallas-based Southwest bought in 2011. The fleets will be combined under the Southwest brand by year's end.

Federal limits on long-haul flights from Dallas Love Field will be lifted in mid-October, clearing the way for new nonstop flights.
