These figures cover 253 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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 2264 flies
UA 2264 flies IAD to BNA without a single fixed slot. Its most common scheduled departure was 17:55, used on 123 of 253 flights, with 17:42 (41 flights) and 17:45 (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 17:55 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2264 runs 7 points better at 75.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
UA 2264 quarter by quarter
Quarter by quarter UA 2264 held fairly steady: 77.6% in Oct–Dec 2025, 78.5% in Jan–Mar 2026 and 70.0% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202576 flights77.6%
- Jan–Mar 202681 flights78.5%
- Apr–Jun 202690 flights70.0%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2264 did best on Thursday at 81.1% on time and worst on Sunday at 63.9%. Each day rests on about 36 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2264 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 5,350 reported delay minutes.
- 40%Late-arriving aircraft
- 25%National Airspace System
- 25%Carrier
- 10%Extreme weather
40% 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 5,350 reported delay minutes here, that single category outweighs weather by 4 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 5,350 delay minutes reported on UA 2264.
Cancellations are rare at 0.79%, 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. 10.0% 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 542 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 four other city pairs in the data, including SMF to IAD (170), IAD to PDX (49) and BNA to ORD (17), but none flew often enough under UA 2264 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to BNA only.
One caution: this is a thin sample. 253 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
