Across the year
UA 1267 quarter by quarter
UA 1267 did not run the same all year. Its best quarter was Jan–Mar 2026 at 63.6% on time and its weakest Apr–Jun 2026 at 15.3%, a swing of 48 points on roughly 67 flights a quarter.

Share of 268 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 115 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 55 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 1267
The latest arrival of the period was on 17 May 2026, 6 hours 8 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across May, June, July and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 May 2026 | 6 hours 8 minutes | National Airspace System |
| 8 June 2026 | 5 hours 55 minutes | Carrier |
| 22 July 2026 | 4 hours 26 minutes | Late-arriving aircraft |

Delay causes
Why UA 1267 runs late
National Airspace System accounts for 67% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 67%National Airspace System
- 25%Late-arriving aircraft
- 8%Carrier
- 0%Extreme weather
67% 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 7,075 minutes out of 11,000, against a national NAS share of 21%. The split is drawn from 10,629 delay minutes reported on UA 1267.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
23.1% 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.
The same number turns up on thirteen other city pairs in the data, including SFO to MCO (41), IAH to LAS (31) and FLL to IAH (30), but none flew often enough under UA 1267 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAS to SFO only.
One caution: this is a thin sample. 268 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 1267
For a booking, UA 1267 is a flight to put a long connection behind. 23.1% 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.
