Republic Airways at Pittsburgh carries a cancellation problem, not just a delay problem: 3.5% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, more than four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 11,641 flights, of which Delta Air Lines flew 3,305 at 87.1% on time.
Measured against the airport rather than the country, Republic Airways runs 2 points ahead of the 80.8% weighted average across all carriers at PIT. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#2
Of 12 carriers clearing the floor at PIT
These figures cover 12,000 flights between September 2025 and August 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Against the competition
Every carrier at PIT, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 87.1% of the time; Envoy Air manages 65.9%. Sample sizes sit next to every figure, because a two-point gap across 386 flights means less than a ten-point one.

| Envoy Air | 386 | 65.9% | 63 min | 2.85% | C |
PSA Airlines cancels 7.4% 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 Republic Airways flies from PIT
Republic Airways operates 10 routes out of PIT 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 22 points, against 21 points between the best and worst carrier.
- 5am–8am3,185 flights92.8%
- 8am–11am2,826 flights86.6%
- 11am–2pm1,944 flights82.0%
- 2pm–5pm1,401 flights73.9%
- 5pm–8pm2,050 flights70.7%
- 8pm–5am235 flights81.5%
Scale runs 60% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.8% of the time, against 70.7% for the evening window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 3,185 flights scheduled in it.
Across the year
Seasonal pattern
December is the weak month at 75.8% on time, against 90.4% in May. 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 1,052 flights.

47% 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 63,000 minutes out of 133,000, against a national NAS share of 21%. The split is drawn from 132,837 reported delay minutes.
Cancellations run at 3.54%, 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.
6.7% of arrivals land an hour or more late, close to the national 8.3%, so 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 sample behind these figures is 11,641 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.
Put together: the delay figures matter less here than the 3.54% cancellation rate. A late arrival costs you a little over 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. 11,217 completed flights over 12 months sit behind that.
Common questions
Republic Airways at PIT
How often is Republic Airways at PIT delayed?
About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 16.8% of the 11,641 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Republic Airways at PIT?
Delta Air Lines leads at 87.1% on time across 3,305 flights. Envoy Air is at the other end on 65.9%, a gap of 21 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 Republic Airways at PIT?
The 5am–8am departure window is the strongest at 92.8% on time. The 5pm–8pm window is the weakest at 70.7%, 22 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 Republic Airways at PIT?
December is the weakest month at 75.8% on time, compared with 90.4% in May. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
