Across the year

B6 1146 quarter by quarter

B6 1146 did not run the same all year. Its best quarter was Apr–Jun 2026 at 80.0% on time and its weakest Jan–Mar 2026 at 50.0%, a swing of 30 points on roughly 88 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 1146 did best on Wednesday at 76.9% on time and worst on Sunday at 52.1%. Each day rests on about 50 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1146 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 7,676 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.

55% 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 7,676 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 7,676 delay minutes reported on B6 1146.

Cancellations sit at 2.27% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

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. 11.6% 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 806 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 353 flights under B6 1146 in the data flew FLL to RIC. 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. 353 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.
