17 of 79 late departures made up the time and arrived on time, 22% of them. In the other direction, 23 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 IND.

|---|---|---|
| 3 August 2026 | 5 hours 7 minutes | Late-arriving aircraft |
| 6 March 2026 | 3 hours 45 minutes | Late-arriving aircraft |

Delay causes
Why UA 1199 runs late
Late-arriving aircraft accounts for 66% of the 5,797 delay minutes carriers reported here, and the remaining four split what is left.
- 66%Late-arriving aircraft
- 17%National Airspace System
- 15%Carrier
- 2%Extreme weather
66% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,797 reported delay minutes here, that single category outweighs weather by 36 to one. The split is drawn from 5,797 delay minutes reported on UA 1199.
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
9.7% 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 976 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 FCA to DEN (144) and RNO to DEN (19), but none flew often enough under UA 1199 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to IND only.
One caution: this is a thin sample. 344 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 1199
