Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5549, 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 5549 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 3.8 hours. That rests on 325 flights, with a median arrival 9 minutes early.

Set against the rest of the country, OO 5549's record is 7 points better than the US average of 77.6%. That gap is worth roughly 71 fewer late arrivals for every thousand flights.

These figures cover 325 flights between July 2025 and June 2026. Beyond the headline rate, 10.9% 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 5549 flies

OO 5549 flies RDD to SFO without a single fixed slot. Its most common scheduled departure was 06:15, used on 102 of 325 flights, with 06:05 (77 flights) and 05:00 (49 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 06:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5549 runs 5 points worse at 84.7%. 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 5549 quarter by quarter

OO 5549 did not run the same all year. Its best quarter was Jul–Sep 2025 at 88.0% on time and its weakest Oct–Dec 2025 at 76.1%, a swing of 12 points on roughly 81 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 202584 flights88.0%
Oct–Dec 202570 flights76.1%
Jan–Mar 202684 flights86.9%
Apr–Jun 202687 flights86.2%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5549 did best on Sunday at 92.9% on time and worst on Wednesday at 78.7%. Each day rests on about 46 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5549 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 11,000 reported delay minutes.

Extreme weather
39%
Late-arriving aircraft
29%
Carrier
22%
National Airspace System
11%

Extreme weather accounts for 39% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 6.2 times the usual weather exposure. The split is drawn from 11,068 delay minutes reported on OO 5549.

Cancellations sit at 1.23% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 10.9% 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 ABQ to IAH (1), but none flew often enough under OO 5549 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDD to SFO only.

One caution: this is a thin sample. 325 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.
