This route sits in the middle of the pack with a B+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 3,680 flights, of which Spirit Airlines flew 956 at 78.4% on time.
Spirit Airlines is the most reliable of the three carriers covered here at 78.4% on time across 956 flights.

These figures cover 3,680 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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
Which airline is most reliable on DTW to MCO
The three carriers here are closely matched: 4 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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Spirit Airlines | 956 | 78.4% | 65 min | 0.94% | B+ |
| Frontier Airlines | 427 | 76.1% | 103 min | 1.41% | B |
| Delta Air Lines | 2,170 | 74.6% | 71 min | 0.92% | C+ |
| Southwest Airlinesthin sample | 127 | 69.0% | 56 min | 0.00% | C+ |
No carrier stands out. Spirit tops the table at 78.4%, 4 points clear of the bottom, which is inside the range this kind of sample moves year to year.
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 25 points, against 4 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am831 flights87.9%
- 8am–11am750 flights80.3%
- 11am–2pm523 flights76.4%
- 2pm–5pm705 flights67.1%
- 5pm–8pm546 flights68.0%
- 8pm–5am325 flights62.6%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 62.6% on time, against 87.9% 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 5am–8am window is the busiest, with 831 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 26 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.
January is the weak month at 61.2% on time, against 86.8% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 413 flights.
Across the week, Tuesday is the strongest day at 79.7% on time and Sunday the weakest at 69.2%. 11 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. Carrier accounts for 45% of the 64,000 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.
- 45%Carrier
- 29%Late-arriving aircraft
- 26%National Airspace System
- 1%Extreme weather
- 0%Security
The largest share of delay minutes, 45%, 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 29,000 of the 64,000 delay minutes reported here. The split is drawn from 64,237 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 87.9% on time here.
Cancellations sit at 0.95% against a national 1.81%, which is ordinary. Diversions add another 0.49%.
Connections and stage length
What a delay here actually costs
8.4% 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 are the a little over an hour kind, which a normal layover absorbs.
The 957 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 73.3% on time across 3,676 flights, within 2 points 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 3,680 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. September runs 86.8% on time and January 61.2%, a swing of 26 points. If the dates move at all, move them out of January before you think about anything else. 3,627 completed flights over 12 months sit behind that.
Common questions
DTW to MCO questions
How often is DTW to MCO delayed?
About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 24.4% of the 3,680 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on DTW to MCO?
Spirit Airlines leads at 78.4% on time across 956 flights. Delta Air Lines is at the other end on 74.6%, a gap of 4 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on DTW to MCO?
The 5am–8am departure window is the strongest at 87.9% on time. The 8pm–5am window is the weakest at 62.6%, 25 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 January delays on DTW to MCO?
January is the weakest month at 61.2% on time, compared with 86.8% in September. Across the year that is 26 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
