Spirit flies to dozens of top destinations—domestic and international. Here are carry-on tips tailored to some of their most popular routes:

Domestic Top Destinations (U.S.)

  • Orlando (MCO) & Miami (MIA): Pack travel-sized sunscreen (3.4oz max) and a compact umbrella in your personal item. Theme park tickets and a reusable water bottle (empty, to fill at the airport) are must-haves.
  • Las Vegas (LAS): Bring a small crossbody bag for your phone, wallet, and casino cards—easy to carry while exploring the Strip. A light jacket is smart (casinos are cold).
  • New York (JFK): Use a durable backpack for walking around the city. Pack a foldable tote bag—great for souvenirs without paying for an extra carry-on.

International Key Routes

  • Cancun (CUN) & Punta Cana (PUJ): Pack a swim suit in your personal item—you can hit the beach right after landing. Travel-sized bug spray and aloe vera are essentials.
  • Bogota (BOG) & Lima (LIM): Bring a reusable water bottle (altitude in Bogota can make you thirsty) and a light sweater (even tropical cities have cool nights).
