This route lands a B+, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 804 MCO to MHT flights, with a median arrival 4 minutes early.
Best time to fly MCO to MHT: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 85.1% of the time and Tuesday flights 84.0%, against 77.6% 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 804 flights between September 2025 and August 2026. The median arrival is 4 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 Orlando to Manchester
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. 3 of the top 4 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 29 points, against half a point between the best and worst carrier.

The 5pm–8pm window is where this operation falls apart: 56.5% on time, against 85.1% for the 8am–11am 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 11am–2pm window is the busiest, with 300 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 42 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 48.6% on time, 42 points below September, the best at 90.6%. 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. May was the busiest month here, with 97 flights.
Across the week, Tuesday is the strongest day at 84.0% on time and Saturday the weakest at 70.0%, a spread of 14 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 47% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 29%Carrier
- 16%National Airspace System
- 6%Extreme weather
- 1%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 10,971 reported delay minutes.
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 85.1% on time here.
Cancellations are rare at 0.62%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here actually costs
6.4% 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 1,142 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 runs 79.6% on time across 804 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.
One caution: this is a thin sample. 804 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 this route
Put together: treat all of this as provisional. 804 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 77.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 798 completed flights over 12 months sit behind that.
Common questions
MCO to MHT questions
How often is MCO to MHT 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 22.4% of the 804 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is MCO to MHT compared with the rest of the country?
77.6% of flights arrive on time here against a national 77.3%, a difference of half a point in its favour. That is worth a B+ on this site's grading scale.
What time of day has the fewest delays on MCO to MHT?
The 8am–11am departure window is the strongest at 85.1% on time. The 5pm–8pm window is the weakest at 56.5%, 29 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 MCO to MHT?
August is the weakest month at 48.6% on time, compared with 90.6% in September. Across the year that is 42 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
