B6 2186 lands a B−, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average.

These figures cover 278 flights between July 2025 and June 2026. The median arrival is 10 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 2186 flies

B6 2186 flies PIT to BOS without a single fixed slot. Its most common scheduled departure was 08:00, used on 49 of 278 flights, with 19:45 (43 flights) and 07:00 (28 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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 2186 runs 5 points worse at 79.4%. 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 2186 quarter by quarter

B6 2186 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.0% on time and its weakest Jul–Sep 2025 at 70.9%, a swing of 16 points on roughly 70 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 202590 flights79.8%
Jan–Mar 202655 flights77.6%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, B6 2186 did best on Saturday at 92.3% on time and worst on Sunday at 64.3%. Each day rests on about 40 flights, so a gap of 28 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 2186 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 5,200 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
46%
Late-arriving aircraft
35%
National Airspace System
19%
Extreme weather
1%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,200 reported delay minutes here, that single category outweighs weather by 35 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,200 delay minutes reported on B6 2186.

Cancellations run at 5.76%, against 1.81% nationally. That is roughly one flight in fifteen 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

7.6% 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 an hour and a half, which a normal layover absorbs.

Every one of the 278 flights under B6 2186 in the data flew PIT to BOS. 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. 278 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 2186

For a booking, the cancellation rate is the figure to plan around on B6 2186: 5.76% of its 278 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.
