About Frontier Airlines
Frontier Airlines is a US ultra-low-cost carrier, which basically means it's built around one idea: get the base fare as low as possible and charge separately for everything else. It's not trying to be Delta. It operates out of four main hubs — Denver (DEN) being the biggest with 56 routes, followed by Orlando (MCO), Atlanta (ATL), and Las Vegas (LAS). The network is almost entirely domestic, with 705 routes inside the US alone, plus some reach into the Caribbean and Latin America. It's a point-to-point operation, not a hub-and-spoke airline you'd build a round-the-world trip around.
Why fly Frontier Airlines?
Honestly, the main reason people pick Frontier is price. If you're flexible and you pack light, you can find fares that genuinely undercut most of the competition on domestic routes. The network has real scale too — 764 non-stop routes across 94 airports means it's not just serving the obvious city pairs. They cover a solid chunk of the Caribbean, with 17 routes into Puerto Rico and 12 into the Dominican Republic, which makes it worth checking if you're planning a warm-weather escape from the eastern US. Their frequent flyer program exists, though it's not the reason most people come back. The animals on the tail fins are a nice touch — every plane has one, which sounds gimmicky but somehow works.

Tips for booking Frontier Airlines
Read the fare rules before you get excited about that cheap ticket. Frontier's base fares often don't include a carry-on bag, and the fees add up fast if you're not paying attention. Book directly through their site and consider their discount club membership if you fly them more than a couple of times a year — it can make the ancillary costs more predictable. DEN and MCO are their strongest hubs, so connections through either tend to have more options. Frontier isn't in a major alliance, so don't expect to earn miles elsewhere or use lounge access. Travel light, book early, and read the fine print.
