Which Miami airport should you fly from?

MIA and FLL compared on 619,160 departures, July 2023 – July 2026: how often flights arrive on time, how often they are cancelled, how long they taxi, and how all of it changes with the time of day. Add a destination to compare the routes each airport flies there.

Enter an airport code. You get the route from each of MIA, FLL to it, side by side. The suggestions are places at least two of these airports fly to.

What stands out in the Miami area

Each line is worked out from the figures below. A lead is claimed only where it is larger than chance.

  • On-time arrivalMIA had the best on-time arrival rate, 73.2%, ahead of FLL at 72.6%. Best to worst is 0.6 points, a difference larger than chance but under a point.
  • CancellationsFLL cancelled 1.70% of its flights, 1.1 times the rate at MIA (1.49%).
  • Taxi timeTaxi-out averages 21.3 min at MIA and 17.8 min at FLL, 3.5 minutes more between pushback and wheels-up. Coming in, taxi time runs from 7.4 min at FLL to 9.8 min at MIA.
  • Time of dayMIA is clearly ahead in 4 of 6 departure windows (12–3 PM, 3–6 PM, 6–9 PM, and 9 PM–5 AM); in the other 2 no airport leads clearly. The gap is widest for departures at 9 PM–5 AM (MIA 69.2% against FLL 59.0%) and narrowest at 5–9 AM (0.1 points).
  • Hour by hourThe biggest swing through the day is at FLL: 5 AM–6 AM reached 91.7% on time (4,075 flights) and 9 PM–10 PM fell to 58.0% (9,988), 33.7 points apart.
  • AirlinesAmerican Airlines flies 56% of departures from MIA, more than any other carrier at any airport here. The largest carrier at each: American Airlines at MIA (56%) and Spirit Airlines at FLL (24%). Carriers with 500 or more departures at only one of them: Envoy Air and Republic Airways at MIA and Allegiant Air at FLL.
  • Destinations71 destinations outside the metro area get 750 or more flights from these airports; 50 of them from at least two and 50 from every airport. MIA alone serves 11 destinations (6% of its departures), including Key West (EYW), Tallahassee (TLH), and Savannah (SAV).
  • Same destinationsOn the 50 destinations every airport serves, on-time arrival runs from 72.8% at FLL to 72.8% at MIA: 0.0 points, narrower than the 0.6 points over all their flights, so part of the overall gap comes from where each airport flies; no airport leads clearly.

MIA and FLL side by side

Every flight that left each airport, July 2023 – July 2026. The same measures as the compare tool, so a figure here is the figure there.

MIA is clearly ahead on 4 of 4 rates.

A check mark and green mark the best figure in a row (higher for on-time rates, lower for delays and cancellations) when it is clearly better than the other’s: a two-proportion test on each airport’s flight count, at about 95% confidence. Otherwise the row says “too close to call”. Average and median delay carry no sample-error estimate here, so they are marked by the printed figure alone.

Share of the metro is each airport’s part of the 619,160 departures at these 2 airports. Taxi-out is pushback to wheels-up on departure and taxi-in is touchdown to gate on arrival, averaged over all flights. The score is the FlyerIntel Reliability Score, 0 to 100.

Each chart has its own scale, so read the numbers in the table, not the bar heights, when comparing airports. The best and worst of 24 hours are the two extremes, so a small airport’s best hour is partly luck; the flight count is beside each. A swing under 3 points, or one the two hours’ flight counts cannot separate from chance, is marked as within noise.

50 places get 750 or more flights from each of MIA and FLL. Counting only flights to those places (91% of MIA’s and 91% of FLL’s departures):

The same airline at different airports

Where one airline flies from several of these airports, its own on-time rate at each. The airline is the same, so a gap is not about who flies, though the routes each flies from an airport still differ.

What these figures do not compare

Reasons two airports can differ that have nothing to do with how well either is run.

  • Different airlines. American Airlines flies 56% of MIA’s departures; Spirit Airlines flies 24% of FLL’s departures. An airline brings its own schedule, aircraft and habits to an airport, so part of every gap above is a gap between carriers.
  • Different destinations. 6% of MIA’s departures and 6% of FLL’s departures go to places no other airport here serves. An on-time arrival is counted at the far end, so weather and congestion at the destination are in the figure.
  • Different trip lengths. The average route, weighted by flights, is 1,044 miles from MIA and 1,052 miles from FLL. Short regional hops and long coast-to-coast flights fail in different ways.
  • Ground time belongs to the airport. Taxi-out and the share of flights that push back on time measure the airport itself. On-time arrival measures the whole trip.
  • History, not a forecast. These are flights from July 2023 – July 2026. A storm cancels hundreds of flights together, so a clear gap is a statement about this sample, not a promise about your trip.
