This route carries a cancellation problem, not just a delay problem: 3.9% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about two flights in three arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 942 CRW to ORD flights, with a median arrival 2 minutes late.
Best time to fly CRW to ORD: a 2pm–5pm departure, ideally on a Monday. Flights in that window arrived on time 76.7% of the time and Monday flights 70.6%, against 64.3% for the route overall.
The national on-time rate over the same period is 77.3%, so this route runs 13 points behind the country as a whole. Across a thousand flights that is about 130 extra late arrivals.

The 5pm–8pm window is where this operation falls apart: 47.5% on time, against 76.7% for the 2pm–5pm 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 5pm–8pm window is the busiest, with 339 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 22 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 50.0% on time, against 72.1% in April. 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, Monday is the strongest day at 70.6% on time and Friday the weakest at 58.6%, a spread of 12 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 33,000 reported delay minutes.
- 40%Carrier
- 28%Late-arriving aircraft
- 24%National Airspace System
- 9%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 13,000 of the 33,000 delay minutes reported here. The split is drawn from 33,414 reported delay minutes.
Cancellations run at 3.93%, against 1.89% 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 actually costs
16.2% 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 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 60.8% on time across 942 flights, 4 points below 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 3.93% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 899 completed flights over 12 months sit behind that.
Common questions
CRW to ORD questions
How often is CRW to ORD delayed?
About 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 35.7% of the 942 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
How reliable is CRW to ORD compared with the rest of the country?
64.3% of flights arrive on time here against a national 77.3%, a difference of 13 points against it. That is worth a D− on this site's grading scale.
What time of day has the fewest delays on CRW to ORD?
The 2pm–5pm departure window is the strongest at 76.7% on time. The 5pm–8pm window is the weakest at 47.5%, 29 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 CRW to ORD?
December is the weakest month at 50.0% on time, compared with 72.1% in April. Across the year that is 22 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
