Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on BTV to PHL carries a cancellation problem, not just a delay problem: 7.1% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four 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 828 flights, with a median arrival 11 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate PSA on BTV to PHL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
PSA against every carrier on BTV to PHL
PSA flew 828 of the 1,145 flights on BTV to PHL, most of the route. Its 76.3% on time is about level with the route as a whole at 76.7%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Republic at 90.3% to American at 69.1%. Two 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 PSA runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 22 points, against half a point between the best and worst carrier.
- 5am–8am268 flights83.4%
- 8am–11am23 flights—
- 11am–2pm181 flights85.2%
- 2pm–5pm172 flights63.1%
- 5pm–8pm184 flights68.3%
- 8pm–5am—
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 85.2% on time, ahead of 2pm–5pm at 63.1%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5am–8am window is the busiest, with 268 flights scheduled in it.
Across the year
PSA on BTV to PHL through the year
December is the weak month at 55.4% on time, against 89.7% 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. January was the busiest month here, with 93 flights.
Across the week, Tuesday is the strongest day at 83.2% on time and Sunday the weakest at 67.9%, a spread of 15 points.
Arrival by arrival
How late PSA on BTV to PHL runs when it is late
PSA on BTV to PHL often beats the schedule: 337 of 769 completed flights, 44%, arrived 15 minutes or more early. The 182 late arrivals split 48 under half an hour, 50 between 30 and 60 minutes, and 84 an hour or more.

Share of 769 completed flights by arrival against schedule.
30 of 172 late departures made up the time and arrived on time, 17% of them. In the other direction, 40 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PHL.
The worst days
Worst days for PSA on BTV to PHL
The latest arrival of the period was on 9 November 2025, 19 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 19 hours 23 minutes | Carrier |
| 19 December 2025 | 17 hours 39 minutes | Late-arriving aircraft |
| 20 August 2026 | 15 hours 25 minutes | Carrier |
| 24 June 2026 | 8 hours 38 minutes | Late-arriving aircraft |
| 23 November 2025 | 6 hours 16 minutes | Carrier |
Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 52% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 30%Carrier
- 11%National Airspace System
- 7%Extreme weather
- 0%Security
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 19,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 18,718 reported delay minutes.
Cancellations run at 7.13%, against 1.89% nationally. That is about one flight in fifteen 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
10.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 73.2% on time across 828 flights, 3 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 3 points of difference.
One caution: this is a thin sample. 828 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 PSA on BTV to PHL
Put together: the delay figures matter less here than the 7.13% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 769 completed flights over 12 months sit behind that.
