Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5899, 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 5899 earns a D, which is as low as this site's scale goes for a reason. Only 57.0% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average roughly 50 minutes. Treat any tight connection here as a coin flip. That rests on 315 flights, with a median arrival 7 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5899 runs 21 points behind the country as a whole. Across a thousand flights that is about 206 extra late arrivals.

These figures cover 315 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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 5899 flies

OO 5899 flies RNO to SFO without a single fixed slot. Its most common scheduled departure was 10:45, used on 58 of 315 flights, with 10:43 (52 flights) and 11:38 (41 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 10:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5899 runs 27 points worse at 57.0%. 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

OO 5899 quarter by quarter

OO 5899 did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.8% on time and its weakest Apr–Jun 2026 at 28.9%, a swing of 53 points on roughly 79 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 5899 did best on Tuesday at 71.7% on time and worst on Friday at 46.5%. Each day rests on about 45 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5899 runs late

One category carries most of the weight here. National Airspace System accounts for 61% of the 6,325 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Extreme weather
2%

61% 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 3,846 minutes out of 6,325, against a national NAS share of 21%. The split is drawn from 6,325 delay minutes reported on OO 5899.

Cancellations sit at 1.59% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

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. 10.0% 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 one other city pair in the data, including ORD to SDF (31), but none flew often enough under OO 5899 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RNO to SFO only.

One caution: this is a thin sample. 315 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
