These figures cover 333 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% 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 2033 flies

B6 2033 flies BOS to IAH without a single fixed slot. Its most common scheduled departure was 12:48, used on 56 of 333 flights, with 10:19 (40 flights) and 08:00 (35 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 12:48 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 2033 runs 7 points worse at 72.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 2033 quarter by quarter

B6 2033 did not run the same all year. Its best quarter was Apr–Jun 2026 at 80.2% on time and its weakest Jul–Sep 2025 at 67.1%, a swing of 13 points on roughly 83 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.

Jul–Sep 202584 flights67.1%
Oct–Dec 202584 flights67.9%
Jan–Mar 202674 flights73.2%
Apr–Jun 202691 flights80.2%

Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, B6 2033 did best on Wednesday at 78.6% on time and worst on Thursday at 66.0%. Each day rests on about 48 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 2033 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,366 reported delay minutes.

Late-arriving aircraft
36%
Carrier
32%

36% 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 5,366 reported delay minutes here, that single category outweighs weather by 24 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 5,366 delay minutes reported on B6 2033.

Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 9.1% 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.

At 1,597 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 333 flights under B6 2033 in the data flew BOS to IAH. 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. 333 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.
