This route lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 1,773 BUF to MCO flights, of which JetBlue Airways flew 535 at 77.0% on time.
Best time to fly BUF to MCO: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 90.3% of the time and Wednesday flights 81.4%, against 76.2% for the route overall.
The US average over the same twelve months is 77.6%, 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 1,773 flights between July 2025 and June 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.
Carrier by carrier
Which airline is most reliable on BUF to MCO
The two carriers here are closely matched: about a point 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 |
|---|---|---|---|---|---|
| JetBlue Airways | 535 | 77.0% | 75 min | 1.87% | B |
| Southwest Airlines | 949 | 75.9% | 52 min | 0.63% | B+ |
| Frontier Airlinesthin sample | 289 | 75.7% | 106 min | 1.38% | B |
No carrier stands out. JetBlue tops the table at 77.0%, about a point clear of the bottom, which is inside the range this kind of sample moves year to year.

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.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. BUF → MCOBuffalo to Orlando | JetBlue Airways | 75.6% | 77.0% | 1.87% | 5am–8am, Fri | B6 85 08:00 |
| 2. BUF → MCOBuffalo to Orlando | Southwest Airlines | 75.4% | 75.9% | 0.63% | 5am–8am, Wed | — |
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 about a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am507 flights90.3%
- 8am–11am310 flights80.6%
- 11am–2pm292 flights76.4%
- 2pm–5pm228 flights60.6%
- 5pm–8pm290 flights62.1%
- 8pm–5am146 flights69.0%
Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.3% of the time, against 60.6% 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 507 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.
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 81.4% on time and Sunday the weakest at 69.4%. 12 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. Late-arriving aircraft accounts for 45% of the 28,000 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%Late-arriving aircraft
- 29%Carrier
- 25%National Airspace System
- 1%Extreme weather
- 0%Security
45% 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 28,000 reported delay minutes here, that single category outweighs weather by 45 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 28,187 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 90.3% on time here.
Cancellations sit at 1.13% against a national 1.81%, which is ordinary. Diversions add another 0.51%.
Connections and stage length
What a delay here actually costs
7.1% 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 1,011 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. 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 68.1% on time across 1,771 flights, 8 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 8 points of difference.
The sample behind these figures is 1,773 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. 1,744 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 23.8% of the 1,773 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on BUF to MCO?
JetBlue Airways leads at 77.0% on time across 535 flights. Southwest Airlines is at the other end on 75.9%, a gap of about a point. 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 90.3% on time. The 2pm–5pm window is the weakest at 60.6%, 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.
