These figures cover 326 flights between July 2025 and June 2026. The median arrival is 8 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 1173 flies

B6 1173 flies JFK to BNA without a single fixed slot. Its most common scheduled departure was 13:30, used on 60 of 326 flights, with 10:37 (40 flights) and 06:30 (38 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 13:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 1173 runs 3 points worse at 75.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 1173 quarter by quarter

By weekday, B6 1173 did best on Tuesday at 85.4% on time and worst on Thursday at 64.6%. Each day rests on about 47 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

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 4,184 reported delay minutes.

Carrier
38%
National Airspace System
32%

Extreme weather

The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,579 of the 4,184 delay minutes reported here. The split is drawn from 4,184 delay minutes reported on B6 1173.

Cancellations run at 3.37%, against 1.81% nationally. That is about one flight in 30 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 about 55 minutes, which a normal layover absorbs.

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. 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 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: 3.37% of its 326 scheduled flights did not operate. A late arrival costs about 55 minutes, but a cancellation costs the day, so leave a later option open.
