Historical statistics for July 2025 to June 2026, not live status. For today’s B6 183, check with JetBlue Airways.
B6 183 lands a B, 4 points better than the national rate of 77.6%. About one flight in six 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 318 flights, with a median arrival 7 minutes early.
Set against the rest of the country, B6 183's record is 4 points better than the US average of 77.6%. That gap is worth roughly 43 fewer late arrivals for every thousand flights.

These figures cover 318 flights between July 2025 and June 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.
Schedule
When B6 183 flies
B6 183 flies JFK to MCO without a single fixed slot. Its most common scheduled departure was 08:10, used on 90 of 318 flights, with 08:00 (63 flights) and 08:29 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 183 runs 2 points worse at 81.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
B6 183 quarter by quarter
B6 183 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.3% on time and its weakest Jul–Sep 2025 at 73.9%, a swing of 21 points on roughly 80 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202588 flights75.6%
- Jan–Mar 202652 flights84.0%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, B6 183 did best on Wednesday at 88.4% on time and worst on Tuesday at 75.0%. Each day rests on about 45 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 183 runs late
One category carries most of the weight here. Carrier accounts for 47% of the 3,256 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.
- 47%Carrier
- 40%National Airspace System
- 7%Extreme weather
- 6%Late-arriving aircraft
The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,536 of the 3,256 delay minutes reported here. The split is drawn from 3,256 delay minutes reported on B6 183.
Cancellations run at 2.52%, against 1.81% nationally. That is about one flight in 40 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
Badly late arrivals are rare here: only 4.2% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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. 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.
Every one of the 318 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. 318 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: 2.52% of its 318 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
