A 10:01 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 1739 runs 8 points worse at 75.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 1739 quarter by quarter
UA 1739 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.2% on time and its weakest Oct–Dec 2025 at 56.9%, a swing of 33 points on roughly 71 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1739 did best on Wednesday at 91.9% on time and worst on Saturday at 61.0%. Each day rests on about 40 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

Share of 277 completed flights by arrival against schedule.
7 of 54 late departures made up the time and arrived on time, 13% of them. In the other direction, 21 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 MCO.
The worst days
Worst days for UA 1739
The latest arrival of the period was on 9 November 2025, 7 hours 30 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across November, October, January, December and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 7 hours 30 minutes | National Airspace System |
| 30 October 2025 | 5 hours 49 minutes | Extreme weather |
| 26 January 2026 | 5 hours 3 minutes | Carrier |
| 14 December 2025 | 5 hours | Late-arriving aircraft |
| 16 March 2026 | 3 hours 10 minutes | Extreme weather |
Delay causes
Why UA 1739 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 5,208 reported delay minutes.
- 41%National Airspace System
- 27%Late-arriving aircraft
- 22%Carrier
- 10%Extreme weather
41% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,128 minutes out of 5,208, against a national NAS share of 21%. The split is drawn from 5,208 delay minutes reported on UA 1739.
Cancellations sit at 2.12% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
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 937 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 ORF to EWR (49), MCO to DEN (38) and PWM to EWR (36), but none flew often enough under UA 1739 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to MCO only.
One caution: this is a thin sample. 283 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 1739
