Quick Summary
- Miami International sits closer to Florida City and the Overseas Highway start.
- Fort Lauderdale can win on flight price and a calmer terminal experience.
- Compare both airports, then plan departure to reach Key Largo in daylight.
The Overseas Highway begins after Florida City and rolls through Key Largo, Islamorada and the Seven Mile Bridge to Key West. If the goal is a relaxed first day, start where you face fewer urban miles. For many travellers that means arranging car hire at Miami International so you can point the bonnet south quickly.
Is Miami usually the easier start?
From MIA you can join the expressways toward Florida City with minimal detours, then settle into US-1 for the coastal run. The terminal area is busy at peaks, but signage is clear and rental shuttles are frequent. If you prefer to collect right at the terminal, the MIA counters keep the process straightforward.
When does Fort Lauderdale make sense?
Flight choice, fares and arrival time can tip the scales. FLL can feel calmer at certain hours and sometimes saves money, though you will add extra miles across Broward and Miami-Dade before you reach US-1. If you choose this route, review timings on our Fort Lauderdale page and plan a comfortable window to reach Key Largo before dusk.
Which vehicle classes suit the Keys?
Space and comfort help on a full day of bridges. Families often enjoy the room in our people carrier options, while travellers with snorkel gear or cameras like the height of an SUV choice. Whether you start at MIA or FLL, keep the first leg easy by packing water and planning beach stops for stretch breaks.
Tolls, timing and one-way ideas
Leaving either airport may involve tolled expressways depending on your route and time of day. Tolls are handled on your agreement, and cashback on tolls is available on many itineraries. If you prefer not to backtrack at the end, compare a round trip with a one-way return from Key West; availability and fees vary by date. For a step-by-step plan of photo stops and beach breaks, skim our Miami to Key West guide while mapping the day.

Which airport usually gets me to the Keys fastest?
Miami is closer to Florida City, so it often means fewer urban miles before US-1. Fort Lauderdale can still be a smart choice if flights or timings suit you better.
Are there tolls on the way out of the airports?
Often yes, depending on your route and hour. Your agreement handles tolls, and cashback on tolls may apply.
Should I plan a one-way to Key West?
It can save time, but it depends on dates and fees. Compare options in the search before you decide.
