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 a little over an hour behind schedule. That rests on 1,813 BUF to MCO flights, of which JetBlue Airways flew 562 at 78.1% on time.

Best time to fly BUF 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 80.1%, against 75.4% 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 1,813 flights between September 2025 and August 2026. The median arrival is 3 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

Which airline is most reliable on BUF to MCO

The two carriers here are closely matched: 3 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.

Best ways to make this trip

The most reliable ways to fly Buffalo to Orlando

Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.

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 30 points, against 3 points between the best and worst carrier.

Scale runs 50% to 95%.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.9% of the time, against 60.1% for the afternoon window. That is 30 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 496 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.

On-time rate by calendar month75J76F68M76A84M80J71J71A82S89O79N60D
Darker means more delays. Figures are on-time percentages.October best, December worst

December is the weak month at 60.4% on time, against 88.8% in October. 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 185 flights.

Across the week, Wednesday is the strongest day at 80.1% on time and Sunday the weakest at 67.2%, a spread of 13 points.

Delay causes

Why this route gets delayed

Late-arriving aircraft accounts for 46% of the 30,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    46%
  • Carrier
    30%
  • National Airspace System
    23%
  • Extreme weather
    1%
  • Security
    0%

46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 30,000 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 29,867 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 89.9% on time here.

Cancellations sit at 1.82% against a national 1.89%, which is ordinary. Diversions add another 0.39%.

Connections and stage length

What a delay here actually costs

7.7% 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 a little over an hour, which a normal layover absorbs.

The 1,011 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 66.4% on time across 1,811 flights, 9 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 9 points of difference.

The sample behind these figures is 1,813 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. October runs 88.8% on time and December 60.4%, a swing of 28 points. If the dates move at all, move them out of December before you think about anything else. 1,773 completed flights over 12 months sit behind that.

Common questions

BUF to MCO questions

How often is BUF 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 24.6% of the 1,813 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on BUF to MCO?

JetBlue Airways leads at 78.1% on time across 562 flights. Southwest Airlines is at the other end on 75.0%, a gap of 3 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 BUF to MCO?

The 5am–8am departure window is the strongest at 89.9% on time. The 2pm–5pm window is the weakest at 60.1%, 30 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 December delays on BUF to MCO?

December is the weakest month at 60.4% on time, compared with 88.8% in October. 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.
