Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on PIT to MCO lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 129 flights. The strongest carrier on the route with a full sample, Spirit Airlines, flew 435 at 80.4% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Frontier on PIT to MCO from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 129 flights between July 2025 and June 2026. Beyond the headline rate, 11.0% 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
Frontier against every carrier on PIT to MCO
Frontier flew 129 of the 2,184 flights on PIT to MCO, about 6% of it. Its 76.4% on time is 3 points worse than the route as a whole, which runs 79.7%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Republic at 82.1% to Frontier at 76.4%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: half a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

| Spirit Airlines | 435 | 80.4% | 73 min | 3.68% | B− |

Spirit Airlines cancels 3.7% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Departure window
When Frontier runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 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–8am—
- 8am–11am25 flights—
- 11am–2pm16 flights—
- 2pm–5pm4 flights—
- 5pm–8pm39 flights59.0%
- 8pm–5am45 flights77.3%
Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 59.0% on time, against 77.3% for the 8pm–5am 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 8pm–5am window is the busiest, with 45 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 76.4% on time across 129 flights.
Split by quarter, Frontier on PIT to MCO logged 36 flights in Jul–Sep 2025, 21 flights in Oct–Dec 2025, 14 flights in Jan–Mar 2026 and 58 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 76.4% annual figure is the one to use.
Across the week, Sunday is the strongest day at 80.0% on time and Friday the weakest at 75.0%. 5 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 63% of the 2,132 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.
- 63%Late-arriving aircraft
- 22%National Airspace System
- 15%Carrier
63% 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 2,132 reported delay minutes here, that single category outweighs weather by 63 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 2,132 reported delay minutes.
Cancellations are rare at 0.78%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
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. 11.0% 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.
The 834 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 78.9% on time across 128 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 129 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Frontier on PIT to MCO
Put together: treat all of this as provisional. 129 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 76.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 127 completed flights over 12 months sit behind that.
