Delay causes
Why UA 1673 runs late
Late-arriving aircraft accounts for 43% of the 7,589 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 32%Carrier
- 22%National Airspace System
- 2%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,589 reported delay minutes here, that single category outweighs weather by 20 to one. The split is drawn from 7,589 delay minutes reported on UA 1673.
Cancellations run at 3.59%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
16.7% 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 802 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.
UA 1673 is not only a ORD to DFW flight. It also flew CLE to ORD (304 flights, 52.9% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 306 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.
