Florida airports and their flight routes
This page puts the 3 Florida airports this site tracks side by side: FLL, MIA and MCO. Counting an airport on a route when it carries at least 5% of the route's passengers, together they cover 19 of the busiest US routes in 2025, 9 more than FLL alone.
The airports
An airport counts on a route when it carries at least 5% of the route's passengers, the same rule as the airport pages. Smaller shares aren't counted, so an airport can have a few passengers on a route without it appearing here. "Routes" is how many of the tracked routes each airport counts on. "Only here" is how many of those have no other airport on this page at 5% or more. This covers the Florida airports with their own airport page, not every airport in the state.
| Airport | Routes | Only here |
|---|---|---|
| Fort Lauderdale-Hollywood (FLL) | 10 | 0 |
| Miami International Airport (MIA) | 10 | 0 |
| Orlando International Airport (MCO) | 9 | 9 |
Where the airports overlap
10 of the 19 routes have more than one of these airports with at least 5% of their passengers, and 9 have just one. On New York to Miami, 2 of them clear that share: FLL and MIA.
- MCO is the only airport here with at least 5% of 9 routes, including New York to Orlando and Washington, DC to Orlando.
Flight CO2 across these routes
The lowest-CO2 route here is Atlanta to Orlando, at 71 kg per passenger over 404 miles. The highest is Los Angeles to Miami, at 292 kg over 2,342 miles. Longer trips burn more fuel, so this range shows how far people fly, not which airport is cleaner.
Every route in one table, 2025

Which state an airport is in comes from Wikidata, traced from each airport's location up to the state, retrieved 2026-11-06. Each step below links to the saved Wikidata record.

- MCO: Orlando International Airport > Orlando > Orange County > Florida.
The airline filings don't split fuel by airport. The CO2 figures cover every airport on a city pair, so they can't show how switching airports changes emissions. Selected and rounded airport shares aren't added into state passenger or emissions totals. Fuel burned only is counted, without non-CO2 warming effects.
