Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on PHL to ATL earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 156 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 3,029 at 84.9% on time.
Set against the rest of the country, Republic's PHL to ATL record is 13 points better than the US average of 77.6%. That gap is worth roughly 125 fewer late arrivals for every thousand flights.

Every carrier on PHL to ATL, 5,713 flights
These figures cover 156 flights between July 2025 and June 2026. The median arrival is 12 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.
Carrier by carrier
Republic against every carrier on PHL to ATL
Republic flew 156 of the 5,713 flights on PHL to ATL, about 3% of it. Its 90.1% on time is 11 points better than the route as a whole, which runs 79.2%. Ranked by on-time rate it is first of six carriers on the route, where the range runs from Republic at 90.1% to Spirit at 60.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 84.9% of the time; Frontier Airlines manages 66.4%. Sample sizes sit next to every figure, because a two-point gap across 1,008 flights means less than a ten-point one.

PSA Airlines cancels 4.1% 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.
Departure window
When Republic runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 156 flights.
- 5am–8am47 flights88.9%
- 8am–11am52 flights94.2%
- 11am–2pm14 flights—
- 2pm–5pm15 flights—
- 5pm–8pm28 flights—
- 8pm–5am—
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 94.2% on time for the 8am–11am window against 88.9% for 5am–8am. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am window is the busiest, with 52 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 90.1% on time across 156 flights.
Split by quarter, Republic on PHL to ATL logged 74 flights in Jul–Sep 2025, 19 flights in Oct–Dec 2025, 28 flights in Jan–Mar 2026 and 35 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 90.1% annual figure is the one to use.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 1,399 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.
- 44%Late-arriving aircraft
- 36%Carrier
- 20%National Airspace System
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,399 reported delay minutes here, that single category outweighs weather by 44 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,399 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 498 of the 1,399 delay minutes reported here.
Cancellations run at 3.21%, against 1.81% 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.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 666 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 runs 90.7% on time across 156 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 156 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 Republic on PHL to ATL
Put together: the delay figures matter less here than the 3.21% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 151 completed flights over 12 months sit behind that.
