Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5448, 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 5448 draws a D. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 365 flights, with a median arrival 3 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5448 runs 15 points behind the country as a whole. Across a thousand flights that is about 153 extra late arrivals.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 15.5% 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 5448 flies

OO 5448 is scheduled to leave Chicago (ORD) at 13:55 local time and reach Fort Wayne (FWA) at 16:10. That slot held for 299 of the 365 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 13:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5448 runs 17 points worse at 62.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5448 quarter by quarter

OO 5448 did not run the same all year. Its best quarter was Oct–Dec 2025 at 72.2% on time and its weakest Jul–Sep 2025 at 55.6%, a swing of 17 points on roughly 91 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 202592 flights55.6%
Oct–Dec 202592 flights72.2%
Jan–Mar 202690 flights64.0%
Apr–Jun 202691 flights57.3%

Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5448 did best on Thursday at 78.0% on time and worst on Saturday at 54.9%. Each day rests on about 52 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5448 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 10,000 reported delay minutes.

Carrier
35%
Late-arriving aircraft
33%
National Airspace System
26%
Extreme weather
7%

The largest share of delay minutes, 35%, 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 3,618 of the 10,000 delay minutes reported here. The split is drawn from 10,484 delay minutes reported on OO 5448.

Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.82%.

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. 15.5% 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 FAR to ORD (6), but none flew often enough under OO 5448 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to FWA only.

One caution: this is a thin sample. 365 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 5448

For a booking, OO 5448 is a flight to put a long connection behind. 15.5% 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.
