Frontier Group Holdings Inc., the parent company of Frontier Airlines, is making significant strides in expanding its reach as a low-fare carrier. The airline is offering promotional fares as low as $38 roundtrip to a diverse array of U.S. and international destinations. This initiative is part of a broader effort to rebrand and enhance its customer service, introducing features like UpFront Plus seating with extra legroom and a guaranteed empty middle seat. Additionally, Frontier plans to debut First Class seating later this year, maintaining its commitment to affordability without compromising comfort. The airline is also rolling out unlimited companion travel for its most loyal patrons, reflecting its commitment to providing flexible and budget-friendly travel options.
