Across the year
UA 752 quarter by quarter

Share of 296 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 71 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 44 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 DCA.
The worst days
Worst days for UA 752
The latest arrival of the period was on 27 July 2026, 9 hours 38 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 July 2026 | 9 hours 38 minutes | Late-arriving aircraft |
| 6 March 2026 | 9 hours 2 minutes | Late-arriving aircraft |
| 29 April 2026 | 4 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why UA 752 runs late
Late-arriving aircraft accounts for 45% of the 8,434 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 39%National Airspace System
- 11%Carrier
- 5%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,434 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 8,434 delay minutes reported on UA 752.
Cancellations are rare at 0.66%, 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
14.9% 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 612 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 fourteen other city pairs in the data, including FLL to ORD (103), TPA to ORD (37) and RSW to ORD (30), but none flew often enough under UA 752 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to DCA only.
One caution: this is a thin sample. 302 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 752
For a booking, UA 752 is a flight to put a long connection behind. 14.9% 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.
