This route 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 942 ORD to CRW flights, with a median arrival 5 minutes late.
Best time to fly ORD to CRW: a 8am–11am departure, ideally on a Wednesday. Flights in that window arrived on time 78.1% of the time and Wednesday flights 67.9%, against 60.8% for the route overall.
The national on-time rate over the same period is 77.3%, so this route runs 17 points behind the country as a whole. Across a thousand flights that is about 165 extra late arrivals.

The 5pm–8pm window is where this operation falls apart: 47.2% on time, against 78.1% for the 8am–11am 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 2pm–5pm window is the busiest, with 345 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 39 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
December is the weak month at 41.0% on time, against 80.0% in October. 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. May was the busiest month here, with 105 flights.
Across the week, Wednesday is the strongest day at 67.9% on time and Sunday the weakest at 53.5%, a spread of 14 points.
Delay causes
Why this route gets delayed
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 31,000 reported delay minutes.
- 34%Late-arriving aircraft
- 34%Carrier
- 22%National Airspace System
- 10%Extreme weather
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 31,000 reported delay minutes here, that single category outweighs weather by 3 to one. The split is drawn from 30,768 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 78.1% on time here.
Cancellations run at 3.18%, against 1.89% nationally. That is about one flight in 30 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 actually costs
18.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 416 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 64.3% on time across 942 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. 942 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 this route
Put together: the delay figures matter less here than the 3.18% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 903 completed flights over 12 months sit behind that.
Common questions
ORD to CRW questions
How often is ORD to CRW delayed?
Roughly one flight in three arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 39.2% of the 942 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is ORD to CRW compared with the rest of the country?
60.8% of flights arrive on time here against a national 77.3%, a difference of 17 points against it. That is worth a D− on this site's grading scale.
What time of day has the fewest delays on ORD to CRW?
The 8am–11am departure window is the strongest at 78.1% on time. The 5pm–8pm window is the weakest at 47.2%, 31 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on ORD to CRW?
December is the weakest month at 41.0% on time, compared with 80.0% in October. Across the year that is 39 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
