Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on MEM to PHL lands a B, 4 points better than the national rate of 77.6%. About one flight in five arrives 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 208 flights, with a median arrival 10 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on MEM to PHL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on MEM to PHL, 758 flights
These figures cover 208 flights between July 2025 and June 2026. The median arrival is 10 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 MEM to PHL
Republic flew 208 of the 758 flights on MEM to PHL, about 27% of it. Its 81.2% on time is about level with the route as a whole at 82.4%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from PSA at 82.9% to Republic at 81.2%.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Republic runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am32 flights90.3%
- 8am–11am49 flights75.0%
- 11am–2pm74 flights87.3%
- 2pm–5pm15 flights—
- 5pm–8pm38 flights83.8%
- 8pm–5am—
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.3% of the time, against 75.0% for the morning window. That is 15 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 74 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 81.2% on time across 208 flights.
Republic on MEM to PHL did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.1% on time and its weakest Oct–Dec 2025 at 75.4%, a swing of 14 points on roughly 69 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Saturday is the strongest day at 87.1% on time and Sunday the weakest at 75.0%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 2,345 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.
- 48%Late-arriving aircraft
- 32%Carrier
- 11%National Airspace System
- 9%Extreme weather
48% 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 2,345 reported delay minutes here, that single category outweighs weather by 5 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 2,345 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.3% on time here.
Cancellations sit at 2.40% against a national 1.81%, which is ordinary. Diversions add another 0.48%.
Connections and stage length
What a delay here costs
5.4% 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 about an hour, which a normal layover absorbs.
The 875 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 84.0% on time across 208 flights, within 3 points 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. 208 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 MEM to PHL
Put together: treat all of this as provisional. 208 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 81.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 202 completed flights over 12 months sit behind that.
