Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Delta Air Lines.
Delta on AUS to MCO lands a B, 4 points better than the national rate of 77.6%. About one flight in five 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 547 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Delta on AUS to MCO from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on AUS to MCO, 2,792 flights
These figures cover 547 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.
Carrier by carrier
Delta against every carrier on AUS to MCO
Delta flew 547 of the 2,792 flights on AUS to MCO, about 20% of it. Its 81.1% on time is 8 points better than the route as a whole, which runs 72.9%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Delta at 81.1% to Spirit at 62.9%. 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 Delta runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 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–11am365 flights89.4%
- 11am–2pm2 flights—
- 2pm–5pm180 flights64.0%
- 5pm–8pm—
- 8pm–5am—
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 89.4% of the time, against 64.0% for the afternoon window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 365 flights scheduled in it.
Across the year
Delta on AUS to MCO through the year
November is the best month on the calendar at 100.0% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. March was the busiest month here, with 62 flights.
Across the week, Tuesday is the strongest day at 88.3% on time and Saturday the weakest at 72.0%. 16 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Delta runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,193 reported delay minutes.
- 33%Carrier
- 32%Late-arriving aircraft
- 29%National Airspace System
- 6%Extreme weather
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 89.4% on time here. The split is drawn from 6,193 reported delay minutes.
No single cause dominates. carrier at 33%, late-arriving aircraft at 32% and national airspace system at 29% split the 6,193 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around.
Cancellations sit at 1.46% against a national 1.81%, which is ordinary. Diversions add another 0.73%.
Connections and stage length
What a delay here costs
5.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 runs 81.1% on time across 547 flights, within half a point 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. 547 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 Delta on AUS to MCO
Put together: treat all of this as provisional. 547 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 81.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 535 completed flights over 12 months sit behind that.
