This route sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 1,865 ORF to ORD flights, of which Envoy Air flew 397 at 76.7% on time.
Best time to fly ORF to ORD: a 8am–11am departure, ideally on a Thursday. Flights in that window arrived on time 85.9% of the time and Thursday flights 79.1%, against 75.9% for the route overall.
Envoy Air is the most reliable of the three carriers covered here at 76.7% on time across 397 flights.

These figures cover 1,865 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% 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
Which airline is most reliable on ORF to ORD
The three carriers here are closely matched: 3 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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| SkyWest Airlinesthin sample | 156 | 85.8% | 88 min | 0.64% | A+ |
| Envoy Air | 397 | 76.7% | 66 min | 2.02% | B |
| Republic Airways | 430 | 75.8% | 62 min | 3.02% | B− |
| PSA Airlinesthin sample | 186 | 74.9% | 81 min | 7.53% | C− |
| United Airlines | 690 | 73.7% | 71 min | 1.74% | C |
| American Airlinesthin sample | 6 | 50.0% | 29 min | 0.00% | F+ |
Republic Airways cancels 3.0% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Best ways to make this trip
The most reliable ways to fly Norfolk to Chicago
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. ORF → ORDNorfolk to Chicago | Envoy Air | 75.2% | 76.7% | 2.02% | 5am–8am, Sat | — |
| 2. ORF → ORDNorfolk to Chicago | Republic Airways | 73.5% | 75.8% | 3.02% | 5am–8am, Thu | — |
| 3. ORF → ORDNorfolk to Chicago | United Airlines | 72.4% | 73.7% | 1.74% | 5am–8am, Thu | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 3 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am665 flights82.9%
- 8am–11am204 flights85.9%
- 11am–2pm253 flights81.6%
- 2pm–5pm172 flights70.4%
- 5pm–8pm526 flights62.0%
- 8pm–5am45 flights78.6%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 62.0% on time, against 85.9% 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 5am–8am window is the busiest, with 665 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.
July is the worst month at 63.4% on time, 22 points below May, the best at 85.1%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 210 flights.
Across the week, Thursday is the strongest day at 79.1% on time and Sunday the weakest at 74.0%. 5 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. National Airspace System accounts for 43% of the 30,000 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.
- 43%National Airspace System
- 25%Late-arriving aircraft
- 24%Carrier
- 7%Extreme weather
43% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 13,000 minutes out of 30,000, against a national NAS share of 21%. The split is drawn from 30,306 reported delay minutes.
Cancellations run at 2.57%, against 1.81% nationally. That is about one flight in 40 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
8.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 717 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 71.8% on time across 1,863 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.
The sample behind these figures is 1,865 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. May runs 85.1% on time and July 63.4%, a swing of 22 points. If the dates move at all, move them out of July before you think about anything else. 1,809 completed flights over 12 months sit behind that.
Common questions
ORF to ORD questions
How often is ORF to ORD delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 24.1% of the 1,865 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on ORF to ORD?
Envoy Air leads at 76.7% on time across 397 flights. United Airlines is at the other end on 73.7%, a gap of 3 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on ORF to ORD?
The 8am–11am departure window is the strongest at 85.9% on time. The 5pm–8pm window is the weakest at 62.0%, 24 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 July delays on ORF to ORD?
July is the weakest month at 63.4% on time, compared with 85.1% in May. 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.
