Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.

Republic on BTV to PHL lands a B−, 3 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 an hour and a half on average. That is a workable record, not a spotless one. That rests on 162 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 BTV 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 BTV to PHL, 1,099 flights

These figures cover 162 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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.

Carrier by carrier

Republic against every carrier on BTV to PHL

Republic flew 162 of the 1,099 flights on BTV to PHL, about 15% of it. Its 80.5% on time is 4 points better than the route as a whole, which runs 77.0%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 80.5% to American at 69.4%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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 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 162 flights.

5am–8am33 flights93.8%
8am–11am—
11am–2pm49 flights89.8%
2pm–5pm31 flights—
5pm–8pm49 flights85.4%
8pm–5am—

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.8% of the time, against 85.4% for the evening window. That is 8 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 49 flights scheduled in it.

Across the year

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.5% on time across 162 flights.

Republic on BTV to PHL did not run the same all year. Its best quarter was Oct–Dec 2025 at 90.9% on time and its weakest Jul–Sep 2025 at 47.1%, a swing of 44 points on roughly 54 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.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 2,861 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.

Late-arriving aircraft
51%
Extreme weather
22%
National Airspace System
18%
Carrier
9%

Extreme weather accounts for 22% 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 3.6 times the usual weather exposure. The split is drawn from 2,861 reported delay minutes.

51% 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 2,861 reported delay minutes here, that single category outweighs weather by 2 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.

Cancellations run at 4.94%, against 1.81% nationally. That is about one flight in twenty 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

8.4% 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 an hour and a half, which a normal layover absorbs.

At 335 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.

The return leg runs 83.4% on time across 162 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. 162 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 BTV to PHL

Put together: the delay figures matter less here than the 4.94% cancellation rate. A late arrival costs you an hour and a half; 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. 154 completed flights over 12 months sit behind that.
