Departure window
When American runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 69.3% on time against 85.5% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 90 flights scheduled in it.

The worst days
Worst days for American on BTV to PHL
The latest arrival of the period was on 11 July 2026, 5 hours 59 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 |
|---|---|---|
| 11 July 2026 | 5 hours 59 minutes | Late-arriving aircraft |
| 6 July 2026 | 3 hours 21 minutes | Late-arriving aircraft |
| 18 October 2025 | 3 hours 14 minutes | Late-arriving aircraft |
| 24 October 2025 | 3 hours 8 minutes | Carrier |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 56% of the 4,113 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 25%Carrier
- 16%National Airspace System
- 3%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,113 reported delay minutes here, that single category outweighs weather by 22 to one. The split is drawn from 4,113 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 85.5% on time here.
Cancellations sit at 1.57% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
13.3% 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 73.7% on time across 190 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 191 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 American on BTV to PHL
Put together: treat all of this as provisional. 191 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 69.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 188 completed flights over 12 months sit behind that.
