Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on MCO to AUS 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 roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 171 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 547 at 81.1% on time.
Set against the rest of the country, Frontier's MCO to AUS 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.

Every carrier on MCO to AUS, 2,792 flights
These figures cover 171 flights between July 2025 and June 2026. The median arrival is 15 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.
Carrier by carrier
Frontier against every carrier on MCO to AUS
Frontier flew 171 of the 2,792 flights on MCO to AUS, about 6% of it. Its 82.0% on time is 5 points better than the route as a whole, which runs 76.7%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Frontier at 82.0% to Spirit at 72.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 6 points 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.

No carrier stands out. Delta tops the table at 81.1%, 6 points clear of the bottom, which is inside the range this kind of sample moves year to year.
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 24 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am45 flights90.7%
- 8am–11am36 flights97.2%
- 11am–2pm4 flights—
- 2pm–5pm73 flights73.2%
- 5pm–8pm13 flights—
- 8pm–5am—
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 97.2% of the time, against 73.2% for the afternoon window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 73 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 82.0% on time across 171 flights.
Frontier on MCO to AUS did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.3% on time and its weakest Jul–Sep 2025 at 70.7%, a swing of 25 points on roughly 43 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Monday is the strongest day at 84.6% on time and Thursday the weakest at 72.2%. 12 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. National Airspace System accounts for 44% of the 1,457 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.
- 44%National Airspace System
- 28%Carrier
- 20%Late-arriving aircraft
- 7%Extreme weather
44% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 643 minutes out of 1,457, against a national NAS share of 21%. The split is drawn from 1,457 reported delay minutes.
Cancellations sit at 2.34% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.0% 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 994 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 is a different operation and performs like one: it runs 77.1% on time across 171 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 171 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 MCO to AUS
Put together: treat all of this as provisional. 171 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 82.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 167 completed flights over 12 months sit behind that.
