Across the year
UA 2264 quarter by quarter
UA 2264 did not run the same all year. Its best quarter was Jan–Mar 2026 at 78.5% on time and its weakest Jul–Sep 2026 at 53.4%, a swing of 25 points on roughly 78 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.

Share of 309 completed flights by arrival against schedule.
10 of 67 late departures made up the time and arrived on time, 15% of them. In the other direction, 32 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 UA 2264
The latest arrival of the period was on 20 May 2026, 7 hours 53 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 May 2026 | 7 hours 53 minutes | Carrier |
| 16 June 2026 | 5 hours 38 minutes | Late-arriving aircraft |
| 21 July 2026 | 5 hours 21 minutes | Extreme weather |

Delay causes
Why UA 2264 runs late
Late-arriving aircraft accounts for 43% of the 8,110 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 25%National Airspace System
- 17%Carrier
- 15%Extreme weather
Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 8,110 delay minutes reported on UA 2264.
Cancellations are rare at 0.64%, below the national 1.89% 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
12.6% 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 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.
The same number turns up on four other city pairs in the data, including SMF to IAD (108), SLC to IAD (40) and ORD to SFO (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. 312 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 2264
For a booking, UA 2264 is a flight to put a long connection behind. 12.6% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
