These figures cover 275 flights between July 2025 and June 2026. Beyond the headline rate, 9.9% 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 UA 1300 flies
UA 1300 flies DEN to BNA without a single fixed slot. Its most common scheduled departure was 18:10, used on 60 of 275 flights, with 17:30 (39 flights) and 17:55 (37 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 18:10 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1300 runs 8 points better at 75.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
UA 1300 next to DEN to BNA

Across the year
UA 1300 quarter by quarter
UA 1300 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.1% on time and its weakest Jul–Sep 2025 at 65.1%, a swing of 18 points on roughly 69 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.

- Oct–Dec 202577 flights80.5%
- Jan–Mar 202685 flights83.1%
- Apr–Jun 202670 flights68.6%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1300 did best on Saturday at 84.2% on time and worst on Thursday at 65.8%. Each day rests on about 39 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1300 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 64% of the 4,648 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.
- 64%Late-arriving aircraft
- 26%National Airspace System
- 8%Carrier
- 1%Extreme weather
64% 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 4,648 reported delay minutes here, that single category outweighs weather by 45 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 4,648 delay minutes reported on UA 1300.
Cancellations are rare at 0.73%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
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. 9.9% 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 1,013 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.
The same number turns up on five other city pairs in the data, including DEN to DFW (31), BUR to SFO (21) and MCO to DEN (19), but none flew often enough under UA 1300 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BNA only.
One caution: this is a thin sample. 275 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 UA 1300
For a booking, read UA 1300 as 75.8% on time with 0.73% cancelled over 275 flights. Those are rates from the past twelve months, not a forecast for any particular day.
