Across the year

UA 793 quarter by quarter

UA 793 did not run the same all year. Its best quarter was Jan–Mar 2026 at 70.7% on time and its weakest Jul–Sep 2026 at 54.1%, a swing of 17 points on roughly 74 flights a quarter.

Delay causes

Why UA 793 runs late

Late-arriving aircraft accounts for 57% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    57%
  • Carrier
    22%
  • National Airspace System
    18%
  • Extreme weather
    3%

57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 10,016 delay minutes reported on UA 793.

Cancellations run at 2.70%, against 1.89% nationally. That is about one flight in 40 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

19.6% 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.

The same number turns up on six other city pairs in the data, including DCA to ORD (26), SFO to ORD (24) and FLL to EWR (21), but none flew often enough under UA 793 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to DFW only.

One caution: this is a thin sample. 296 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 793

For a booking, the cancellation rate is the figure to plan around on UA 793: 2.70% of its 296 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
