These figures cover 310 flights between September 2025 and August 2026. The median arrival is 2 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
OO 4701 quarter by quarter
OO 4701 did not run the same all year. Its best quarter was Jul–Sep 2026 at 85.4% on time and its weakest Apr–Jun 2026 at 68.9%, a swing of 17 points on roughly 78 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.

By weekday, OO 4701 did best on Tuesday at 81.8% on time and worst on Friday at 65.9%. Each day rests on about 44 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 308 completed flights by arrival against schedule.
8 of 43 late departures made up the time and arrived on time, 19% of them. In the other direction, 34 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 RDD.
The worst days
Worst days for OO 4701
The latest arrival of the period was on 28 December 2025, 4 hours 54 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, March, April and February, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 December 2025 | 4 hours 54 minutes | Carrier |
| 19 December 2025 | 3 hours 9 minutes | Late-arriving aircraft |
| 28 March 2026 | 2 hours 27 minutes | Late-arriving aircraft |

Delay causes
Why OO 4701 runs late
Carrier accounts for 50% of the 3,347 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 29%Late-arriving aircraft
- 18%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,668 of the 3,347 delay minutes reported here. The split is drawn from 3,347 delay minutes reported on OO 4701.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
5.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
The 932 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 four other city pairs in the data, including CAE to ORD (25), DEN to OTH (21) and RNO to SFO (1), but none flew often enough under OO 4701 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to RDD only.
One caution: this is a thin sample. 310 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 OO 4701
