Republic Airways at Philadelphia lands a B−, 5 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 6,782 flights, of which Delta Air Lines flew 6,525 at 82.2% on time.
Measured against the airport rather than the country, Republic Airways runs 7 points ahead of the 75.3% weighted average across all carriers at PHL. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#2
Of 10 carriers clearing the floor at PHL
These figures cover 6,782 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 PHL, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 82.2% of the time; Alaska Airlines manages 67.3%. Sample sizes sit next to every figure, because a two-point gap across 768 flights means less than a ten-point one.

Spirit Airlines cancels 5.7% 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 PHL
Republic Airways operates 25 routes out of PHL 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 15 points between the best and worst carrier.
- 5am–8am484 flights92.0%
- 8am–11am1,864 flights89.2%
- 11am–2pm1,014 flights81.8%
- 2pm–5pm1,080 flights79.4%
- 5pm–8pm1,426 flights75.0%
- 8pm–5am914 flights77.3%
Scale runs 65% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.0% of the time, against 75.0% 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 1,864 flights scheduled in it.
Across the year
Seasonal pattern
August is the worst month at 73.8% on time, 16 points below April, the best at 89.9%. 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. October was the busiest month here, with 671 flights.
Delay causes
What holds this operation up
- 43%Late-arriving aircraft
- 27%National Airspace System
- 21%Carrier
- 9%Extreme weather
- 0%Security
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 90,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 90,472 reported delay minutes.
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.
7.6% 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 6,782 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 3.18% 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. 6,556 completed flights over 12 months sit behind that.
Common questions
Republic Airways at PHL
How often is Republic Airways at PHL 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 17.8% of the 6,782 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 PHL?
Delta Air Lines leads at 82.2% on time across 6,525 flights. Alaska Airlines is at the other end on 67.3%, a gap of 15 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 PHL?
The 5am–8am departure window is the strongest at 92.0% on time. The 5pm–8pm window is the weakest at 75.0%, 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 August delays on Republic Airways at PHL?
August is the weakest month at 73.8% on time, compared with 89.9% in April. Across the year that is 16 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
