US Airways ups ante on PHL-BOS route

Big story in The Inquirer today about US Airways' efforts to protect some of the profits it has made for years on its PHL-BOS route. As you can tell from this page one story, PHL's biggest airline is losing customers to its second-biggest, Southwest, and is offering perks to those flying US on the route. In case you missed it, I pestered Southwest for a couple of years about the need for competition for US Airways on the route, as a way to bring down the exorbitant airfares, and voila! Southwest started flights this summer (because it could make money, not because I pestered their CEO, I hope.)

 As the story says, one of the US Airways perks for customers is special curbside baggage check-in. Question not answered: Will it still cost to check a bag, since Southwest charges nothing?
