These figures cover 271 flights between July 2025 and June 2026. The median arrival is 16 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 1883 flies

B6 1883 flies BOS to RDU without a single fixed slot. Its most common scheduled departure was 06:00, used on 109 of 271 flights, with 07:00 (57 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 1883 runs 2 points worse at 87.0%. 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 1883 quarter by quarter

B6 1883 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.8% on time and its weakest Jan–Mar 2026 at 76.9%, a swing of 19 points on roughly 68 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 1883 did best on Monday at 95.3% on time and worst on Sunday at 80.0%. Each day rests on about 39 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1883 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 1,745 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.

  • Carrier
    50%
  • National Airspace System
    49%
  • Late-arriving aircraft
    1%
  • Extreme weather
    0%

49% 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 853 minutes out of 1,745, against a national NAS share of 21%. The split is drawn from 1,745 delay minutes reported on B6 1883.

Cancellations run at 3.32%, against 1.81% nationally. That is about 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

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 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.

Every one of the 271 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. 271 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: 3.32% of its 271 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
