Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on BUF to MCO lands a B−, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 562 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on BUF to MCO from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 562 flights between September 2025 and August 2026. The median arrival is 7 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
JetBlue against every carrier on BUF to MCO
JetBlue flew 562 of the 1,813 flights on BUF to MCO, about 31% of it. Its 78.1% on time is 3 points better than the route as a whole, which runs 75.4%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from JetBlue at 78.1% to Frontier at 71.3%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.

Departure window
When JetBlue runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against half a point between the best and worst carrier.
- 5am–8am168 flights85.5%
- 8am–11am252 flights80.7%
- 11am–2pm24 flights—
- 2pm–5pm112 flights61.2%
- 5pm–8pm5 flights—
- 8pm–5am1 flights—
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 85.5% of the time, against 61.2% for the afternoon window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 252 flights scheduled in it.
Across the year
JetBlue on BUF to MCO through the year
December is the weak month at 55.6% on time, against 97.1% 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. August was the busiest month here, with 77 flights.
Across the week, Saturday is the strongest day at 81.5% on time and Sunday the weakest at 74.4%, a spread of 7 points.
Arrival by arrival
How late JetBlue on BUF to MCO runs when it is late
JetBlue on BUF to MCO often beats the schedule: 175 of 540 completed flights, 32%, arrived 15 minutes or more early. The 118 late arrivals split 40 under half an hour, 39 between 30 and 60 minutes, and 39 an hour or more.

Share of 540 completed flights by arrival against schedule.
14 of 91 late departures made up the time and arrived on time, 15% of them. In the other direction, 41 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.
The worst days
Worst days for JetBlue on BUF to MCO
The latest arrival of the period was on 9 November 2025, 23 hours 50 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 23 hours 50 minutes | Carrier |
| 1 March 2026 | 9 hours 51 minutes | Late-arriving aircraft |
| 23 December 2025 | 8 hours 34 minutes | Late-arriving aircraft |
| 13 July 2026 | 7 hours 44 minutes | Late-arriving aircraft |
| 31 October 2025 | 3 hours 31 minutes | Carrier |
Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 46% of the 9,382 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 28%Carrier
- 24%National Airspace System
- 2%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,382 reported delay minutes here, that single category outweighs weather by 24 to one. The split is drawn from 9,382 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 85.5% on time here.
Cancellations run at 3.38%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
7.2% 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 65.6% on time across 560 flights, 13 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 13 points of difference.
One caution: this is a thin sample. 562 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 JetBlue on BUF to MCO
Put together: the delay figures matter less here than the 3.38% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 540 completed flights over 12 months sit behind that.
