14 of 76 late departures made up the time and arrived on time, 18% of them. In the other direction, 24 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 BNA.
The worst days
Worst days for B6 1173
The latest arrival of the period was on 18 March 2026, 5 hours 30 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, August, December and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 March 2026 | 5 hours 30 minutes | Carrier |

Delay causes
Why B6 1173 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 5,489 reported delay minutes.
- 36%Carrier
- 33%National Airspace System
- 29%Late-arriving aircraft
- 1%Extreme weather
- 0%Security
33% 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 1,825 minutes out of 5,489, against a national NAS share of 21%. The split is drawn from 5,489 delay minutes reported on B6 1173.
Cancellations run at 6.44%, against 1.89% nationally. That is about 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
11.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 765 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.
Every one of the 326 flights under B6 1173 in the data flew JFK to BNA. 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. 326 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 1173
For a booking, the cancellation rate is the figure to plan around on B6 1173: 6.44% of its 326 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
