Southwest Airlines announced Tuesday that it would start charging passengers to check bags for the first time.The offer of checking two bags for free has long been a popular foundation for the airline. "Two bags fly free" is listed as a registered trademark on Southwest's website.<br /><br />But from May 28, passengers who aren't part of a loyalty program or traveling on its most expensive fare, Business Select, will have to pay to check a bag.<br /><br />Frequent flyers with "A-List Preferred" status will still get two bags, while A-List level members and Southwest credit card holders will get one free checked bag.<br /><br />The airline said the move was intended to "deepen and reward loyalty" for its "most engaged customers."<br /><br />It added that it would also introduce a basic economy fare, with additional options for assigned seating and extra legroom.Charging for luggage is the latest move in the budget carrier's shake-up of its business model — as it has faced pressure from the activist investing firm Elliott Management. Just six months ago, the airline said it wouldn't start charging for bags.
