It's been a good summer for frequent flyers who either live in the Boston area or fly there.
Delta got the bonus ball rolling with a triple elite-qualifying miles promotion for its Shuttle operation, including New York-Boston flights, through August 31.
American responded to a portion of Delta's promotion with its own triple elite-qualifying mile bonus for American or American Eagle flights between New York and Chicago (O'Hare) or Boston, also through August 31.
And now, on the eve of the first anniversary of its service to Boston, Southwest has added its own Boston promotion to the mix.
According to Southwest:
In celebration of one year serving Boston, Southwest Rapid Rewards is offering double credits for members who fly into or out of Boston Logan, Manchester, or Providence between August 12 and October 31.
With the bonus, Rapid Rewards members earn two credits for every one-way flight, four credits for each round-trip.
Registration is required and must be completed by September 15.
Deal or No Deal
Southwest's offer isn't as generous as the other Boston bonuses. But those promotions are limited to specific routes, and most end on August 31.
Double credits, for two and a half months, for any Southwest flight to or from Boston Logan or two nearby airports. That's a decent bonus, on offer for a comfortably long period, for plenty of flights.
