Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5303, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 5303 lands a B+, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 331 flights, with a median arrival 9 minutes early.

These figures cover 331 flights between July 2025 and June 2026. Beyond the headline rate, 9.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When OO 5303 flies

OO 5303 flies DEN to RAP without a single fixed slot. Its most common scheduled departure was 19:10, used on 42 of 331 flights, with 20:30 (39 flights) and 21:04 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:10 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5303 runs 11 points better at 78.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OO 5303 quarter by quarter

OO 5303 did not run the same all year. Its best quarter was Oct–Dec 2025 at 94.4% on time and its weakest Jul–Sep 2025 at 68.2%, a swing of 26 points on roughly 83 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.

Jul–Sep 202585 flights68.2%
Oct–Dec 202573 flights94.4%
Jan–Mar 202689 flights80.9%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5303 did best on Monday at 85.1% on time and worst on Saturday at 70.5%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5303 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 6,152 reported delay minutes.

Carrier
40%
Late-arriving aircraft
33%
National Airspace System
20%
Extreme weather
7%

The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,430 of the 6,152 delay minutes reported here. The split is drawn from 6,152 delay minutes reported on OO 5303.

Cancellations are rare at 0.30%, below the national 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on three other city pairs in the data, including ORD to GSO (16), ORD to GRR (6) and DEN to SUN (1), but none flew often enough under OO 5303 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to RAP only.

One caution: this is a thin sample. 331 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.
