These figures cover 280 flights between September 2025 and August 2026. The median arrival is 17 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.

Delay causes
Why B6 1883 runs late
Carrier accounts for 54% of the 1,996 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 44%National Airspace System
- 2%Late-arriving aircraft
- 0%Extreme weather
44% 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 877 minutes out of 1,996, against a national NAS share of 21%. The split is drawn from 1,996 delay minutes reported on B6 1883.
Cancellations run at 3.93%, 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
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.3% 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 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.
Every one of the 280 flights under B6 1883 in the data flew BOS to RDU. 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. 280 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 1883
For a booking, the cancellation rate is the figure to plan around on B6 1883: 3.93% of its 280 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
