Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5494, 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.

These figures cover 325 flights between July 2025 and June 2026. Beyond the headline rate, 13.8% 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 5494 flies

OO 5494 flies DEN to AMA without a single fixed slot. Its most common scheduled departure was 19:20, used on 85 of 325 flights, with 19:10 (61 flights) and 19:25 (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 19:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5494 runs level with that at 69.0%. 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 5494 quarter by quarter

OO 5494 did not run the same all year. Its best quarter was Oct–Dec 2025 at 82.7% on time and its weakest Jul–Sep 2025 at 51.2%, a swing of 32 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 202586 flights51.2%
Oct–Dec 202582 flights82.7%
Jan–Mar 202677 flights78.4%

Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5494 did best on Sunday at 77.6% on time and worst on Friday at 60.4%. Each day rests on about 46 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5494 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 8,149 reported delay minutes.

Late-arriving aircraft
33%
National Airspace System
27%
Carrier
24%
Extreme weather
16%

Extreme weather accounts for 16% 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 2.6 times the usual weather exposure. The split is drawn from 8,149 delay minutes reported on OO 5494.

Cancellations sit at 1.54% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

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. 13.8% 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 two other city pairs in the data, including ORD to BNA (4) and PSP to LAX (2), but none flew often enough under OO 5494 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to AMA 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.

What to do with this

Booking OO 5494

For a booking, OO 5494 is a flight to put a long connection behind. 13.8% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
