These figures cover 341 flights between September 2025 and August 2026. The median arrival is 6 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.

22 of 74 late departures made up the time and arrived on time, 30% of them. In the other direction, 35 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at IAH.
The worst days
Worst days for B6 2033
The latest arrival of the period was on 6 July 2026, 3 hours 39 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across July, January, March and February, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 July 2026 | 3 hours 39 minutes | Carrier |
| 19 January 2026 | 3 hours 21 minutes | National Airspace System |

Delay causes
Why B6 2033 runs late
National Airspace System accounts for 44% of the 4,494 delay minutes carriers reported here, and the remaining four split what is left.

- 4%Extreme weather
- 0%Security
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 1,969 minutes out of 4,494, against a national NAS share of 21%. The split is drawn from 4,494 delay minutes reported on B6 2033.
Cancellations sit at 2.05% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
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 341 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. 341 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.
