The latest arrival of the period was on 28 March 2026, 7 hours 20 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 |
|---|---|---|
| 28 March 2026 | 7 hours 20 minutes | Carrier |
| 22 July 2026 | 6 hours 58 minutes | Carrier |
| 26 July 2026 | 4 hours 59 minutes | Late-arriving aircraft |

Delay causes
Why UA 2187 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 4,639 reported delay minutes.
- 38%Late-arriving aircraft
- 30%Carrier
- 26%National Airspace System
- 6%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,639 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 4,639 delay minutes reported on UA 2187.
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
9.4% 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 850 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 two other city pairs in the data, including DEN to SJC (83) and MKE to DEN (17), but none flew often enough under UA 2187 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BUR to DEN only.
One caution: this is a thin sample. 256 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 2187
