Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5754, 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 5754 draws a D−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is an hour and a half behind schedule. Build slack into anything you connect to. That rests on 290 flights, with a median arrival 7 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5754 runs 14 points behind the country as a whole. Across a thousand flights that is about 136 extra late arrivals.

These figures cover 290 flights between July 2025 and June 2026. Beyond the headline rate, 14.7% 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 5754 flies

OO 5754 flies DLH to ORD without a single fixed slot. Its most common scheduled departure was 11:20, used on 113 of 290 flights, with 11:14 (58 flights) and 11:27 (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 11:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5754 runs 15 points worse at 64.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5754 quarter by quarter

OO 5754 did not run the same all year. Its best quarter was Oct–Dec 2025 at 78.0% on time and its weakest Apr–Jun 2026 at 54.8%, a swing of 23 points on roughly 73 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 5754 did best on Tuesday at 80.5% on time and worst on Wednesday at 55.0%. Each day rests on about 41 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5754 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 9,132 reported delay minutes.

Late-arriving aircraft
38%
National Airspace System
28%
Carrier
24%
Extreme weather
11%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 9,132 reported delay minutes here, that single category outweighs weather by 3 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 9,132 delay minutes reported on OO 5754.

Cancellations run at 3.79%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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. 14.7% 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 two other city pairs in the data, including SBA to SFO (19) and SFO to BUR (2), but none flew often enough under OO 5754 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DLH to ORD only.

One caution: this is a thin sample. 290 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 5754

For a booking, the cancellation rate is the figure to plan around on OO 5754: 3.79% of its 290 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
