These figures cover 328 flights between September 2025 and August 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

The latest arrival of the period was on 12 June 2026, 11 hours 33 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across June, March, February and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 June 2026 | 11 hours 33 minutes | Late-arriving aircraft |
| 1 March 2026 | 3 hours 26 minutes | Carrier |
| 17 June 2026 | 2 hours 1 minute | Carrier |

Delay causes
Why UA 2412 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 2,347 reported delay minutes.
- 41%Late-arriving aircraft
- 34%Carrier
- 23%National Airspace System
- 3%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,347 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 2,347 delay minutes reported on UA 2412.
Cancellations are rare at 0.30%, 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
Badly late arrivals are rare here: only 3.1% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 1,491 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 three other city pairs in the data, including DEN to CID (35), SMF to SFO (1) and MCO to IAH (1), but none flew often enough under UA 2412 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BWI to DEN only.
One caution: this is a thin sample. 328 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 2412
For a booking, UA 2412 has one of the better records a US domestic flight can show: 88.0% on time and 0.30% cancelled. That is a base rate, not a promise about any single day.
