Book a Flight to the Florida Keys

Fly into Florida Keys for a truly tropical, relaxing stay away from day to day life. Expect palm trees and sea breezes, clear warm waters, and coral reef teeming with fish. Scuba diving, deep sea fishing and sailing are prime pursuits, but you can also stroll around old towns, interesting museums, vibrant festivals and incredible seafood restaurants for the whole family.

While it might feel like you are a million miles from civilization when you are there, flying to Florida Keys is easy. You can fly to the islands from several UK and international airports. When booking your flight, make sure to get a window seat to catch your first glimpse of the islands and coral reefs as you arrive. Seeing the reef from up high really helps you grasp its sheer size and natural beauty.

When to Fly to the Florida Keys

The months of January through to May are the best times to fly to Florida Keys, when the summer humidity has yet to kick in and the weather is ideal for a relaxing break. There are good reasons to come to the Keys throughout the year, though, for snorkelling, scuba diving and fishing and for lively festivals and sport fishing events in the other seasons.

If you’re on a budget, maybe consider the shoulder months of November and December when the weather is still warm, but the hotels are lower-priced and the crowds fewer.

Choose an Airport in Florida Keys

Miami International Airport is one of the United States’ busiest and biggest transport hubs, and if you’re heading to the Keys from Europe, this will be your destination. All major airlines fly to Miami International Airport, and there are some excellent deals to be found on long-haul flights.

From Miami, domestic flights will take you out to airports on Key West and Marathon. While both are international airports, they tend to host mostly domestic air traffic and smaller planes. Several major air carriers have regular schedules out to Marathon and Key West, so you have plenty of choice when it comes to times and connections with your international flight.

In addition to Miami International Airport, Florida is home to several other international airports including Fort Lauderdale, Orlando and Tampa, all of which connect to Florida Keys, so you are really spoilt for choice. You can get both direct and connecting flights from a number of UK airports – Heathrow, Gatwick, Luton, Stansted – with British Airways, Austrian, Air France, Lufthansa, Iberia, United, Delta and Virgin.

Explore the Keys by Floatplane

Getting to some of the most remote parts of Florida Keys can be tricky, and so go for an adventure on a seaplane out to places such as the Dry Tortugas National Park and Fort Jefferson and really get off the beaten track. Some luxury private island resorts offer their guests transfer flights from the main islands by seaplane.
