BGRADE

This route lands a B, 4 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 1,231 PNS to MIA flights, with a median arrival 5 minutes early.

Best time to fly PNS to MIA: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 87.4% of the time and Tuesday flights 87.6%, against 82.0% for the route overall.

Set against the rest of the country, this route's record is 4 points better than the US average of 77.6%. That gap is worth roughly 44 fewer late arrivals for every thousand flights.

These figures cover 1,231 flights between July 2025 and June 2026. The median arrival is 5 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

The flight numbers below flew this route at least 250 times in the period, busiest first. Each has its own record, with its schedule and delay causes.

Departure window

The best time of day to leave

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 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–8am365 flights86.0%
  • 8am–11am239 flights87.4%
  • 11am–2pm
  • 2pm–5pm117 flights73.0%
  • 5pm–8pm508 flights78.7%
  • 8pm–5am2 flights

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 87.4% of the time, against 73.0% for the afternoon window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 508 flights scheduled in it.

Across the year

When delays peak on this route

This route's year swings by 17 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.

On-time rate by calendar month87J85F82M80A82M86J77J72A89S89O84N76D
Darker means more delays. Figures are on-time percentages.October best, August worst

August is the worst month at 72.4% on time, 17 points below October, the best at 89.1%. 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. January was the busiest month here, with 119 flights.

Across the week, Tuesday is the strongest day at 87.6% on time and Sunday the weakest at 74.6%. 13 points is a smaller lever than departure hour, but it is free.

Delay causes

Why this route gets delayed

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 14,000 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
    20%
  • National Airspace System
    19%
  • Extreme weather
    12%

Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 13,657 reported delay minutes.

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 14,000 reported delay minutes here, that single category outweighs weather by 4 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.

Cancellations sit at 1.22% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here actually costs

Badly late arrivals are rare here: only 4.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 530 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 82.8% on time across 1,231 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 1,231 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 this route

Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 89.1% on time and August 72.4%, a swing of 17 points. If the dates move at all, move them out of August before you think about anything else. 1,216 completed flights over 12 months sit behind that.

Common questions

PNS to MIA questions

How often is PNS to MIA delayed?

About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 18.0% of the 1,231 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.

How reliable is PNS to MIA compared with the rest of the country?

82.0% of flights arrive on time here against a national 77.6%, a difference of 4 points in its favour. That is worth a B on this site's grading scale.

What time of day has the fewest delays on PNS to MIA?

The 8am–11am departure window is the strongest at 87.4% on time. The 2pm–5pm window is the weakest at 73.0%, 14 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.

How bad are August delays on PNS to MIA?

August is the weakest month at 72.4% on time, compared with 89.1% in October. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
