This route sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 1,563 MCO to MCI flights, with a median arrival 1 minute early.
Best time to fly MCO to MCI: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 96.7% of the time and Wednesday flights 80.4%, against 71.5% for the route overall.
The national on-time rate over the same period is 77.6%, so this route runs 6 points behind the country as a whole. Across a thousand flights that is about 61 extra late arrivals.

These figures cover 1,563 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% 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 MCO to MCI
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.

|---|---|---|---|---|---|
| Republic Airwaysthin sample | 28 | 85.7% | 28 min | 0.00% | A+ |

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 48 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–8am211 flights96.7%
- 8am–11am286 flights84.2%
- 11am–2pm249 flights75.3%
- 2pm–5pm266 flights70.5%
- 5pm–8pm195 flights62.1%
- 8pm–5am356 flights48.8%
Scale runs 40% to 100%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 48.8% on time, against 96.7% 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 8pm–5am window is the busiest, with 356 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 20 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.
June is the worst month at 62.1% on time, 20 points below November, the best at 82.5%. 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 159 flights.
Across the week, Wednesday is the strongest day at 80.4% on time and Sunday the weakest at 64.5%. 16 points is a smaller lever than departure hour, but it is free.
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 25,000 reported delay minutes.
- 41%Late-arriving aircraft
- 36%Carrier
- 19%National Airspace System
- 3%Extreme weather
- 1%Security
41% 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 25,000 reported delay minutes here, that single category outweighs weather by 14 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 25,212 reported delay minutes.
The largest share of delay minutes, 36%, 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 9,177 of the 25,000 delay minutes reported here.
Cancellations sit at 1.54% against a national 1.81%, which is ordinary. Diversions add another 0.26%.
Connections and stage length
What a delay here actually costs
8.7% 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 1,072 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 1,559 flights, 6 points above 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 6 points of difference.
The sample behind these figures is 1,563 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. November runs 82.5% on time and June 62.1%, a swing of 20 points. If the dates move at all, move them out of June before you think about anything else. 1,535 completed flights over 12 months sit behind that.
Common questions
MCO to MCI questions
How often is MCO to MCI delayed?
Roughly 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 28.5% of the 1,563 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
How reliable is MCO to MCI compared with the rest of the country?
71.5% of flights arrive on time here against a national 77.6%, a difference of 6 points against it. That is worth a C on this site's grading scale.
What time of day has the fewest delays on MCO to MCI?
The 5am–8am departure window is the strongest at 96.7% on time. The 8pm–5am window is the weakest at 48.8%, 48 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 June delays on MCO to MCI?
June is the weakest month at 62.1% on time, compared with 82.5% in November. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
