Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.

SkyWest on ORD to RIC draws a D−. Roughly 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 718 flights. The strongest carrier on the route with a full sample, Envoy Air, flew 379 at 78.9% on time.

The national on-time rate over the same period is 77.6%, so SkyWest on ORD to RIC runs 16 points behind the country as a whole. Across a thousand flights that is about 157 extra late arrivals.

These figures cover 718 flights between July 2025 and June 2026. Beyond the headline rate, 16.6% 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.

Carrier by carrier

SkyWest against every carrier on ORD to RIC

SkyWest flew 718 of the 2,219 flights on ORD to RIC, about 32% of it. Its 61.9% on time is 8 points worse than the route as a whole, which runs 70.2%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Envoy at 78.9% to United at 58.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 2 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Departure window

When SkyWest runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against 2 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am42 flights81.0%
  • 8am–11am228 flights73.1%
  • 11am–2pm82 flights68.3%
  • 2pm–5pm195 flights51.1%
  • 5pm–8pm52 flights50.0%
  • 8pm–5am119 flights50.9%

Scale runs 40% to 85%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 50.0% on time, against 81.0% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 228 flights scheduled in it.

On-time rate by calendar month47JFMA69M74J55J72A78S56O68N38D
Darker means more delays. Figures are on-time percentages.September best, December worst

December is the weak month at 38.0% on time, against 77.8% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 111 flights.

Across the week, Tuesday is the strongest day at 70.3% on time and Friday the weakest at 51.5%. 19 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 49% of the 25,000 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.

  • Carrier
    49%
  • Extreme weather
    25%
  • Late-arriving aircraft
    17%
  • National Airspace System
    9%

Extreme weather accounts for 25% 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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.1 times the usual weather exposure. The split is drawn from 25,112 reported delay minutes.

The largest share of delay minutes, 49%, 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 12,000 of the 25,000 delay minutes reported here.

Cancellations run at 4.32%, 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 stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.6% 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 642 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 66.1% on time across 719 flights, 4 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.

One caution: this is a thin sample. 718 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 SkyWest on ORD to RIC

Put together: the delay figures matter less here than the 4.32% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 685 completed flights over 12 months sit behind that.
