These figures cover 363 flights between July 2025 and June 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.
Schedule
When B6 598 flies
B6 598 flies MCO to LGA without a single fixed slot. Its most common scheduled departure was 08:20, used on 81 of 363 flights, with 06:25 (39 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 08:20 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 598 runs 5 points worse at 79.5%. 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 598 quarter by quarter
B6 598 did not run the same all year. Its best quarter was Jul–Sep 2025 at 92.4% on time and its weakest Apr–Jun 2026 at 59.6%, a swing of 33 points on roughly 91 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.
- Jul–Sep 202592 flights92.4%
- Oct–Dec 202592 flights83.3%
- Jan–Mar 202688 flights82.7%

Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, B6 598 did best on Thursday at 84.3% on time and worst on Sunday at 70.0%. Each day rests on about 52 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 598 runs late
One category carries most of the weight here. National Airspace System accounts for 47% of the 3,758 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%National Airspace System
- 26%Late-arriving aircraft
- 23%Carrier
- 4%Extreme weather
47% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,754 minutes out of 3,758, against a national NAS share of 21%. The split is drawn from 3,758 delay minutes reported on B6 598.
Cancellations run at 2.75%, against 1.81% nationally. That is roughly 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
6.2% 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 roughly 50 minutes, which a normal layover absorbs.
The 950 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 363 flights under B6 598 in the data flew MCO to LGA. 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. 363 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 598
For a booking, the cancellation rate is the figure to plan around on B6 598: 2.75% of its 363 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
