Across the year
UA 1769 quarter by quarter

Share of 274 completed flights by arrival against schedule.
23 of 93 late departures made up the time and arrived on time, 25% of them. In the other direction, 22 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 SFO.
The worst days
Worst days for UA 1769
The latest arrival of the period was on 6 March 2026, 5 hours 8 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as national airspace system delay.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 5 hours 8 minutes | Late-arriving aircraft |
| 7 June 2026 | 4 hours 46 minutes | Late-arriving aircraft |

Delay causes
Why UA 1769 runs late
National Airspace System accounts for 63% of the 7,081 delay minutes carriers reported here, and the remaining four split what is left.
- 63%National Airspace System
- 23%Late-arriving aircraft
- 11%Carrier
- 3%Extreme weather
63% 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 4,466 minutes out of 7,081, against a national NAS share of 21%. The split is drawn from 7,081 delay minutes reported on UA 1769.
Cancellations are rare at 0.72%, 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
13.1% 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.
At 2,400 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on three other city pairs in the data, including SFO to MIA (248), SFO to SMF (12) and SMF to IAH (9), but none flew often enough under UA 1769 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to SFO only.
One caution: this is a thin sample. 277 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 1769
For a booking, UA 1769 is a flight to put a long connection behind. 13.1% 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.
