  • The early bird gets the most rewarding deals, so book as soon as you know your travel dates. The most affordable airfares sell like hotcakes and prices generally rise as the departure date gets closer.
  • Make big savings on your getaway by bundling your flights, hotels and car rental into an Orbitz package deal. Your budget will thank you for it.
  • Don't travel during the busy season if possible. By avoiding summer and school vacations, you can save loads on your airfare.

What do I need for the flight to Key Largo?
The trick to a hassle-free flight is being well prepared. Here are some tips that'll help get you ready for your adventure:

  • Whether you print it out at home or use an electronic one, you'll need your boarding pass to walk on to the plane. You'll also need some type of government-issued photo identification. If you're traveling internationally, make sure your passport is valid and you've looked into visa requirements.
  • To keep you occupied on the short trip to Key Largo, download some new music or restock the audiobook library on your smartphone. Food can also be a good distraction while in the air, so maybe even bring some light snacks.
  • It can get chilly on the plane. If you don't want to shiver your way through the flight, pack an extra layer.

How do I get cheap first-class/business deals to Key Largo?
There are ways of booking first or business-class fares to Key Largo that won't burn through your wallet. Grab a seat in the pointy end of the plane for less with these handy tips:

  • Flexibility isn't just useful for your yoga. Have some room to move around your travel dates so you can pick up cheaper airfares when they crop up.
  • Plenty of low-cost carriers have quality business or premium-class seating that doesn't cost a bundle.
  • Bid for an upgrade in online auctions or upgrade with frequent flyer loyalty programs.

What is the best time to go to Key Largo?
If you'd like to immerse yourself in the culture of Key Largo in the busy season, January, February and March are the prime months to visit. June 20 marks the first day of the summer season in the Northern Hemisphere and is a perfect time to go if you savor the outdoors. At this time, average daily temperatures normally range from 80 ºF to 85 ºF.
Travel tips for Key Largo

  • The downtown area has loads of terrific attractions. Hot spots like Jimmy Johnson's Big Chill and Caribbean Club Bar will keep your feet on the move and the sightseer in you satisfied.
  • You'll discover rewarding day trips a short commute from Key Largo's center. Head for John Pennekamp Coral Reef State Park first and then find time for Homestead-Miami Speedway.
