These figures cover 315 flights between September 2025 and August 2026. The median arrival is 8 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.

Share of 303 completed flights by arrival against schedule.
8 of 44 late departures made up the time and arrived on time, 18% of them. In the other direction, 21 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

The latest arrival of the period was on 16 December 2025, 10 hours 46 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, July, February and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 December 2025 | 10 hours 46 minutes | Carrier |

Delay causes
Why B6 183 runs late
Carrier accounts for 46% of the 3,891 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 37%National Airspace System
- 11%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,783 of the 3,891 delay minutes reported here. The split is drawn from 3,891 delay minutes reported on B6 183.
Cancellations run at 3.81%, against 1.89% nationally. That is about one flight in 25 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 routes
What a delay on this flight costs
5.9% 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 944 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.
Every one of the 315 flights under B6 183 in the data flew JFK to MCO. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 315 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 B6 183
For a booking, the cancellation rate is the figure to plan around on B6 183: 3.81% of its 315 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
