Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.

American on TPA to MIA lands a B+, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 2,567 flights, with a median arrival 8 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate American on TPA to MIA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 2,567 flights between July 2025 and June 2026. Beyond the headline rate, 9.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

American against every carrier on TPA to MIA

American flew 2,567 of the 2,945 flights on TPA to MIA, most of the route. Its 78.0% on time is about level with the route as a whole at 77.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from American at 78.0% to Republic at 61.5%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When American runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 36 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am685 flights92.6%
  • 8am–11am1,013 flights82.7%
  • 11am–2pm49 flights83.7%
  • 2pm–5pm290 flights63.3%
  • 5pm–8pm385 flights57.7%
  • 8pm–5am145 flights56.4%

Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 56.4% on time, against 92.6% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 1,013 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.September best, August worst

August is the worst month at 63.4% on time, 24 points below September, the best at 87.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 250 flights.

Across the week, Tuesday is the strongest day at 84.9% on time and Sunday the weakest at 69.9%. 15 points is a smaller lever than departure hour, but it is free.

Delay causes

Why American runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 58,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Late-arriving aircraft
    49%
  • Carrier
    38%
  • National Airspace System
    9%
  • Extreme weather
    4%
  • Security
    0%

49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 58,000 reported delay minutes here, that single category outweighs weather by 12 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 57,662 reported delay minutes.

The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 22,000 of the 58,000 delay minutes reported here.

Cancellations sit at 0.90% against a national 1.81%, which is ordinary. Diversions add another 0.04%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.6% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 204 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 69.2% on time across 2,569 flights, 9 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 9 points of difference.

The sample behind these figures is 2,567 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking American on TPA to MIA

Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 87.0% on time and August 63.4%, a swing of 24 points. If the dates move at all, move them out of August before you think about anything else. 2,543 completed flights over 12 months sit behind that.
