About Spirit Airlines

Spirit is a US ultra-low-cost carrier — think bare-bones pricing, not business class lounges. It's not part of any major alliance, and it runs a lean, no-frills operation built around one thing: cheap seats. With 378 non-stop routes spread across 65 airports, it punches well above its weight for a budget airline. The network leans heavily domestic — 329 of those routes stay within the US — but it also reaches into Mexico, Colombia, the Dominican Republic, and beyond. Fort Lauderdale (FLL) is the beating heart of the whole operation.

Why fly Spirit Airlines?

Honestly? Price. That's the main reason people choose Spirit, and there's no shame in it. If you're flying somewhere like FLL or MCO and you're flexible with bags and extras, you can score genuinely low base fares. The network is bigger than people realize — 378 routes means real options, not just a handful of tourist runs. I've seen Spirit pop up as the only non-stop option on certain US-to-Caribbean routes, which is actually huge if you hate connections. Their Free Spirit loyalty program lets you earn points even on cheap fares. It's not a premium experience, but if the destination matters more than the ride there, Spirit gets you in the air for less.

Tips for booking Spirit Airlines

Pack light or pay up — Spirit's baggage fees can genuinely flip a "cheap" fare into an expensive one if you're not careful. A personal item fits under the seat for free, but a carry-on? That'll cost you. Book direct through Spirit's site for the best fare visibility. FLL is their strongest hub with 55 routes, so connections through Fort Lauderdale tend to be your most reliable option. Spirit isn't in any alliance, so don't expect to use miles from another program here. First-time flyers: read every checkbox during checkout. There are add-ons hiding everywhere — seat selection, bags, the works. Eyes open.
