Closest airport by total trip fit
Closest Airport to Key West, Florida
EYW is both closest and best for most visitors. Mainland airports trade a larger flight network for a long road journey, while MTH and TMB are aviation-specific branches.
Start here
Price EYW first with the complete island transfer. Compare MIA and FLL only after adding a rental, shuttle, traffic, and the full Overseas Highway drive, keep MTH and TMB for qualifying private or general aviation, and use RSW only for a real Southwest Florida and Keys itinerary.

Six airports compared by total trip fit
| Airport | City | Best for | Skip if |
|---|---|---|---|
| 1. Key West International Airport (EYW) | Key West | nearly every Key West-only trip | a mainland flight creates a much better wider-Keys itinerary |
| 2. Florida Keys Marathon International Airport (MTH) | Marathon | general aviation or a Middle Keys itinerary with arranged aircraft | you need current scheduled airline service to Key West |
| 3. Miami International Airport (MIA) | Miami | a larger network plus a Florida Keys road trip | Key West is the only destination and EYW has a workable flight |
| 4. Fort Lauderdale-Hollywood International Airport (FLL) | Fort Lauderdale | a materially better flight or South Florida open jaw | the extra mainland distance erases the fare advantage |
| 5. Miami Executive Airport (TMB) | Kendall | private aviation followed by a south Miami-Dade departure | you need scheduled passenger service |
| 6. Miami-Opa Locka Executive Airport (OPF) | Opa-locka | private aviation combined with north Miami-Dade | you need scheduled passenger service or a direct island arrival |
Ranked airport cards
Use the first airport that clears every dependency
Key West International Airport
Key West International Airport (EYW) lands travelers directly on Key West and provides the shortest complete arrival. For a Key West, Florida trip, it is most useful for nearly every Key West-only trip, and its smaller-airport schedules and fares still need comparison, but avoiding the mainland drive has substantial value.
Validate before booking: flight, bags, taxi or rideshare, hotel shuttle, weather, and return plan
Florida Keys Marathon International Airport
Florida Keys Marathon International Airport (MTH) serves general aviation in the Middle Keys and sits closer than mainland hubs. For a Key West, Florida trip, it is most useful for general aviation or a Middle Keys itinerary with arranged aircraft, and Monroe County describes current commercial service as a future initiative, so do not treat it as a bookable scheduled substitute.
Validate before booking: operator, current service status, rental or transfer, and Overseas Highway
Miami International Airport
Miami International Airport (MIA) offers the deepest mainland network and the most common drive-to-the-Keys baseline. For a Key West, Florida trip, it is most useful for a larger network plus a Florida Keys road trip, and the full Overseas Highway journey, rental cost, and return buffer must beat the convenience of EYW.
Validate before booking: flight, rental, traffic, weather, road conditions, and return margin
Fort Lauderdale-Hollywood International Airport
Fort Lauderdale-Hollywood International Airport (FLL) adds another broad South Florida route and fare market. For a Key West, Florida trip, it is most useful for a materially better flight or South Florida open jaw, and it starts even farther north than MIA and needs a substantial air or itinerary advantage.
Validate before booking: flight advantage, rental, traffic, road conditions, and return buffer
Miami Executive Airport
Miami Executive Airport (TMB) can support private aviation before a Keys drive from south Miami-Dade. For a Key West, Florida trip, it is most useful for private aviation followed by a south Miami-Dade departure, and it still leaves the long Overseas Highway transfer and is not a normal airline option.
Validate before booking: operator, FBO, vehicle, road conditions, and trip timing
Miami-Opa Locka Executive Airport
Miami-Opa Locka Executive Airport (OPF) adds a private-aviation field in north Miami-Dade. For a Key West, Florida trip, it is most useful for private aviation combined with north Miami-Dade, and it still requires the full Overseas Highway drive and is not a normal airline-booking choice.
Validate before booking: operator, FBO, vehicle, road conditions, weather, and return plan
Service orientation
EYW ends the trip in Key West, while mainland airports create a road trip
EYW removes the multi-hour mainland transfer and offers taxis, rideshares, rental cars, buses, and hotel shuttles. MIA and FLL provide broader networks but turn the arrival into a Florida Keys road trip, while MTH currently remains a general aviation airport with future commercial-service efforts.
The Overseas Highway is a scenic two-lane corridor through much of the Keys, not a short airport transfer. Weather, crashes, holiday demand, bridge work, and the need to return a rental car can make a mainland fare look less attractive after the complete trip is priced.

How the Key West, Florida airport choice actually works
EYW removes the multi-hour mainland transfer and offers taxis, rideshares, rental cars, buses, and hotel shuttles. MIA and FLL provide broader networks but turn the arrival into a Florida Keys road trip, while MTH currently remains a general aviation airport with future commercial-service efforts.
The Overseas Highway is a scenic two-lane corridor through much of the Keys, not a short airport transfer. Weather, crashes, holiday demand, bridge work, and the need to return a rental car can make a mainland fare look less attractive after the complete trip is priced.
Tropical weather, Fantasy Fest, winter demand, holiday traffic, cruise activity, and limited EYW aircraft capacity can affect fares and transfers. Recheck MTH service status and ferry schedules rather than assuming either is a current airline substitute.
Key West, Florida has more than one plausible airport because route networks and road geography point in different directions. MIA serves a larger network plus a Florida Keys road trip; FLL serves a materially better flight or South Florida open jaw; TMB serves private aviation followed by a south Miami-Dade departure; OPF serves private aviation combined with north Miami-Dade; each option remains conditional until the exact flight and transfer are priced together.
The planning bands on this page terminate at Mallory Square in Old Town Key West. Add baggage, rental pickup, tolls, weather, event traffic, and the actual lodging address before deciding that a shorter airfare search result creates a shorter trip.
Booking sequence
Five decisions in dependency order
Build the EYW baseline
Price one workable EYW itinerary to Key West, Florida with bags, arrival time, rental or transfer, and the return journey. This complete baseline gives every alternative a real trip to beat.
Verify the local branch
Check MTH service status, operating days, passenger facilities, and pickup instructions. Do not treat a nearby runway as a scheduled-airline option when the airport is limited, private, seasonal, or general aviation.
Name the alternate advantage
For MIA, FLL, TMB, OPF, identify the nonstop, fare, arrival window, or wider itinerary that creates value. If the advantage cannot be named, keep EYW as the default.
Price the final transfer
Use a live map from the chosen airport to Mallory Square in Old Town Key West for the arrival hour, then add pickup time, toll treatment, parking, equipment, and driver fatigue. The Key West, Florida bands are an early screen, not a promise.
Repeat pre-travel checks
Before travel, recheck the flight, airport notice, rental or shuttle hours, road conditions, and the return buffer. Recheck EYW flight and ground options, MTH service status, Overseas Highway conditions, tropical weather, ferry schedules, and lodging access.
Ranking method
Service, ground friction, total cost, then live controls
Usable flight first
For Key West, Florida, an operating itinerary with recovery choices outranks a closer field that does not fit the ticket.
Ground friction second
Score the route to Mallory Square in Old Town Key West, pickup method, tolls, traffic, weather, and event or seasonal pressure.
Total cost third
Combine fare, bags, rental or transfer, fuel, tolls, parking, lodging, and the value of travel time.
Live conditions last
Recheck EYW flight and ground options, MTH service status, Overseas Highway conditions, tropical weather, ferry schedules, and lodging access. A current disruption can override the evergreen order.

Use bands for planning, then recalculate live
| Airport | Branch | Planning band | Interpretation |
|---|---|---|---|
| EYW | EYW to Mallory Square | About 15 to 30 minutes | default island gateway |
| MTH | MTH to Mallory Square | About 1 hour 10 minutes to 1 hour 45 minutes | Middle Keys aviation branch |
| MIA | MIA to Mallory Square | About 3 hours 15 minutes to 5 hours | mainland road-trip gateway |
| FLL | FLL to Mallory Square | About 3 hours 45 minutes to 5 hours 45 minutes | northern mainland alternative |
| TMB | TMB to Mallory Square | About 3 hours to 4 hours 30 minutes | private mainland branch |
| OPF | OPF to Mallory Square | About 3 hours 20 minutes to 5 hours | northern private mainland branch |
These are deliberately broad planning bands, not live traffic promises. Add baggage, immigration where relevant, rental or ride pickup, tolls, weather, construction, and the exact Key West, Florida arrival point.
Arrival logistics
Four decisions that can change the winner
Exact arrival point
Route to Mallory Square in Old Town Key West, then replace it with the real lodging, campus, park entrance, or meeting address before booking.
Rental or transfer
Compare the full vehicle cost with a prebooked transfer. Include counter hours, equipment, tolls, parking, and the return journey.
Peak conditions
Tropical weather, Fantasy Fest, winter demand, holiday traffic, cruise activity, and limited EYW aircraft capacity can affect fares and transfers. Recheck MTH service status and ferry schedules rather than assuming either is a current airline substitute.
Late arrival
Protect time for bags and pickup on the way to Mallory Square in Old Town Key West. A late landing can make a closer Key West, Florida airport worse when a rental desk, shuttle, road, or destination access point closes.
