A low-cost airline that recently paid a $2.2 million penalty for attempting to deceive its customers during the pandemic has joined a chorus of critique against Southwest Airlines over its recent bag policy shift.

“We’ve always had heart,” Frontier CEO Barry Biffle said in a news release on Tuesday. “Some airlines are walking away from what travelers love, but we’re running towards it. Consider this the ultimate ‘divorce your old airline’ deal.”

Frontier Airlines is stepping up its game. The airline announced Tuesday via press release that it will offer customers a free checked bag on select flights this summer.
