These figures cover 262 flights between July 2025 and June 2026. Beyond the headline rate, 16.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When B6 2184 flies
B6 2184 flies RDU to BOS without a single fixed slot. Its most common scheduled departure was 17:35, used on 48 of 262 flights. 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 17:35 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 2184 runs 5 points worse at 63.4%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
B6 2184 quarter by quarter
B6 2184 did not run the same all year. Its best quarter was Jan–Mar 2026 at 75.7% on time and its weakest Apr–Jun 2026 at 57.4%, a swing of 18 points on roughly 66 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.

By weekday, B6 2184 did best on Saturday at 84.4% on time and worst on Thursday at 44.4%. Each day rests on about 37 flights, so a gap of 40 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 2184 runs late
One category carries most of the weight here. National Airspace System accounts for 43% of the 8,136 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.
- 43%National Airspace System
- 31%Late-arriving aircraft
- 26%Carrier
- 1%Extreme weather
43% 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 3,504 minutes out of 8,136, against a national NAS share of 21%. The split is drawn from 8,136 delay minutes reported on B6 2184.
Cancellations run at 3.05%, against 1.81% nationally. That is roughly 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 routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 612 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 same number turns up on one other city pair in the data, including MCO to JFK (15), but none flew often enough under B6 2184 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to BOS only.
One caution: this is a thin sample. 262 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 2184
For a booking, the cancellation rate is the figure to plan around on B6 2184: 3.05% of its 262 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
