Frontier Airlines: Low Fares, More Travel Frontier Airlines is one of the most recognizable ultra-low-cost carriers (ULCCs) in the United States, offering affordable travel to over 100 destinations across the U.S., Mexico, the Caribbean, and Central America. Founded in 1994 and headquartered in Denver, Colorado, Frontier has built its brand around the belief that air travel should be accessible to everyone. Frontier operates with a “you only pay for what you need” philosophy. The base fare covers your seat and one personal item, while extras like carry-on luggage, checked bags, seat selection, and snacks are available for an additional cost. This flexible pricing model allows travelers to customize their journey based on budget and preference. One of Frontier’s standout features is its commitment to environmental sustainability. The airline operates one of the youngest and most fuel-efficient fleets in the U.S., consisting entirely of Airbus A320 family aircraft. Frontier’s signature animal-themed plane tails and bright green branding reflect its eco-friendly mission and playful personality. Frequent flyers can benefit from the FRONTIER Miles loyalty program, which offers the opportunity to earn miles on every flight and redeem them with no blackout dates. For those who fly often or want extra savings, the Discount Den® membership provides access to exclusive low fares and even cheaper flights for kids on select routes. Frontier is also known for seasonal and ultra-low promotional fares, often available for under $50, making it an ideal option for budget-conscious travelers, families, and students. Despite its stripped-down service model, Frontier delivers where it counts: safe, efficient travel at a fraction of the cost of traditional carriers.
