How Good is Frontier Airlines, It can be a good airline for very specific types of travelers: those who prioritize the absolute lowest fare above all else. As an ultra-low-cost carrier, Frontier excels at providing incredibly cheap base tickets for travel across the U.S., Mexico, and the Caribbean. However, this low price comes with significant trade-offs. The airline operates on a strict à la carte model, meaning everything from carry-on bags and seat selection to a bottle of water costs extra. These fees can add up quickly, making the total cost comparable to a legacy carrier if you need any amenities. The seats have minimal legroom and recline, and the airline has received mixed reviews for customer service and punctuality. For a short, no-frills trip where you can travel with only a small personal item, Frontier offers unbeatable value. But for families, those needing flexibility, or travelers wanting comfort, it is often not the best choice.
