Share of 344 completed flights by arrival against schedule.
13 of 86 late departures made up the time and arrived on time, 15% of them. In the other direction, 30 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 DFW.
The worst days
Worst days for UA 2116
The latest arrival of the period was on 29 November 2025, 5 hours 5 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 November 2025 | 5 hours 5 minutes | Late-arriving aircraft |
| 19 February 2026 | 4 hours 36 minutes | Late-arriving aircraft |
| 16 March 2026 | 4 hours 15 minutes | Late-arriving aircraft |
| 5 July 2026 | 4 hours 12 minutes | National Airspace System |

Delay causes
Why UA 2116 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 7,917 reported delay minutes.
- 42%Late-arriving aircraft
- 29%National Airspace System
- 24%Carrier
- 5%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,917 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 7,917 delay minutes reported on UA 2116.
Cancellations are rare at 0.57%, 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
12.2% 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 1,172 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 ORD to MSP (3) and DFW to DEN (2), but none flew often enough under UA 2116 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to DFW only.
One caution: this is a thin sample. 350 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 2116
For a booking, UA 2116 is a flight to put a long connection behind. 12.2% 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.
