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 77.3%. The late ones land about an hour behind schedule. That rests on 2,707 MDW to MCO flights, with a median arrival 2 minutes early.
Best time to fly MDW to MCO: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 89.9% of the time and Wednesday flights 84.0%, against 75.2% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 2,707 flights between September 2025 and August 2026. The median arrival is 2 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 most reliable ways to fly Chicago to Orlando
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 4 of the top 5 use a different airport at one end.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
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 33 points, against half a point between the best and worst carrier.
- 5am–8am690 flights89.9%
- 8am–11am530 flights81.0%
- 11am–2pm469 flights72.0%
- 2pm–5pm359 flights68.9%
- 5pm–8pm459 flights61.7%
- 8pm–5am200 flights57.4%
Scale runs 50% to 95%.
The 8pm–5am window is where this operation falls apart: 57.4% on time, against 89.9% 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 690 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 28 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.
August is the worst month at 58.5% on time, 28 points below September, the best at 86.8%. 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. March was the busiest month here, with 286 flights.
Across the week, Wednesday is the strongest day at 84.0% on time and Sunday the weakest at 68.1%, a spread of 16 points.
Delay causes
Why this route gets delayed
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 38,000 reported delay minutes.
- 37%Carrier
- 34%Late-arriving aircraft
- 27%National Airspace System
- 2%Extreme weather
- 0%Security
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 38,000 reported delay minutes here, that single category outweighs weather by 22 to one. The split is drawn from 38,331 reported delay minutes.
The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 38,000 delay minutes reported here.
Cancellations sit at 1.55% against a national 1.89%, which is ordinary. Diversions add another 0.70%.
Connections and stage length
What a delay here actually costs
7.6% of arrivals land an hour or more late, close to the national 8.3%, so 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 990 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.
The return leg is a different operation and performs like one: it runs 70.0% on time across 2,723 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.
The sample behind these figures is 2,707 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 August 58.5%, a swing of 28 points. If the dates move at all, move them out of August before you think about anything else. 2,646 completed flights over 12 months sit behind that.
Common questions
MDW to MCO questions
How often is MDW to MCO delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 24.8% of the 2,707 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is MDW to MCO compared with the rest of the country?
75.2% of flights arrive on time here against a national 77.3%, a difference of 2 points against it. That is worth a B on this site's grading scale.
What time of day has the fewest delays on MDW to MCO?
The 5am–8am departure window is the strongest at 89.9% on time. The 8pm–5am window is the weakest at 57.4%, 33 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 MDW to MCO?
August is the weakest month at 58.5% on time, compared with 86.8% in September. Across the year that is 28 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
