Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on PHL to BTV carries a cancellation problem, not just a delay problem: 6.4% 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 C− 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 8 minutes early.
The national on-time rate over the same period is 77.3%, so PSA on PHL to BTV runs 4 points behind the country as a whole. Across a thousand flights that is about 41 extra late arrivals.

Worst days for PSA on PHL to BTV
The latest arrival of the period was on 31 August 2026, 18 hours 18 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 31 August 2026 | 18 hours 18 minutes | Late-arriving aircraft |
| 19 December 2025 | 17 hours 41 minutes | Late-arriving aircraft |
| 31 January 2026 | 12 hours 44 minutes | Late-arriving aircraft |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 59% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 21%Carrier
- 11%National Airspace System
- 10%Extreme weather
59% 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 6 to one. The split is drawn from 18,901 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 86.0% on time here.
Cancellations run at 6.40%, 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
11.8% 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 76.3% on time across 828 flights, 3 points above 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 PHL to BTV
Put together: the delay figures matter less here than the 6.40% 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. 771 completed flights over 12 months sit behind that.
