Envoy Air at Chicago lands a B, 2 points worse than the national rate of 77.6%. About one flight in four arrive 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 57,088 flights, of which JetBlue Airways flew 1,105 at 77.8% on time.
Measured against the airport rather than the country, Envoy Air runs 5 points ahead of the 70.9% weighted average across all carriers at ORD. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#3
Of 12 carriers clearing the floor at ORD
These figures cover 57,000 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% 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.
Against the competition
Every carrier at ORD, ranked
The choice of carrier is not cosmetic here. JetBlue Airways arrives on time 77.8% of the time; PSA Airlines manages 59.9%. Sample sizes sit next to every figure, because a two-point gap across 3,385 flights means less than a ten-point one.

PSA Airlines cancels 6.8% 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.
Route by route
Where Envoy Air flies from ORD
Envoy Air operates 25 routes out of ORD with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against 18 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am2,384 flights86.6%
- 8am–11am14,701 flights81.3%
- 11am–2pm9,051 flights79.9%
- 2pm–5pm10,038 flights75.1%
- 5pm–8pm9,546 flights69.4%
- 8pm–5am11,368 flights70.4%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 86.6% of the time, against 69.4% for the evening window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 14,701 flights scheduled in it.
Across the year
Seasonal pattern
December is the weak month at 61.9% on time, against 85.5% 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. March was the busiest month here, with 5,859 flights.

Extreme weather accounts for 15% 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 2.3 times the usual weather exposure. The split is drawn from 819,630 reported delay minutes.
Cancellations run at 2.82%, against 1.81% nationally. That is roughly 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.
8.5% 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 are the about an hour kind, which a normal layover absorbs.
57,088 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
Put together: the delay figures matter less here than the 2.82% cancellation rate. A late arrival costs you about an hour; 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. 55,355 completed flights over 12 months sit behind that.
Common questions
Envoy Air at ORD
How often is Envoy Air at ORD delayed?
About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.9% of the 57,088 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on Envoy Air at ORD?
JetBlue Airways leads at 77.8% on time across 1,105 flights. PSA Airlines is at the other end on 59.9%, a gap of 18 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 Envoy Air at ORD?
The 5am–8am departure window is the strongest at 86.6% on time. The 5pm–8pm window is the weakest at 69.4%, 17 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 Envoy Air at ORD?
December is the weakest month at 61.9% on time, compared with 85.5% in September. Across the year that is 24 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
