Frontier Airlines has introduced sweeping changes to its product and customer service offerings, ushering in ‘The New Frontier.’ Among the enhancements is UpFront Plus seating, an upgraded seating option with extra leg and elbow room in the first two rows of the aircraft. Customers in UpFront Plus enjoy a window or aisle seat with extra legroom and a guaranteed empty middle seat. In the coming months, the airline will introduce free, unlimited companion travel for its most loyal customers. Debuting in late 2025, Frontier will also begin offering First Class seating on every flight, combining unmatched comfort and space at Frontier’s trademark affordable prices. 

Frontier continues to innovate with its industry-leading frequent flyer program, FRONTIER Miles, which allows customers to ‘Get It All For Less.’ Members earn miles quickly and get rewarded for each dollar spent on Frontier products. Miles accrue based on dollars spent with a standard 10X multiplier: $1 = 10 miles, with multipliers increasing at every elite level up to 20X. Elite status is attainable at only 10,000 miles and offers perks such as priority boarding, seat selection and free bag(s) depending on status level. Like the airline, FRONTIER Miles is also family friendly, offering easy family pooling of miles making it simple for families to enjoy rewards together. Joining is free.
