These figures cover 126 flights between September 2025 and August 2026.

Delay causes

Why Republic runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,411 reported delay minutes.

Extreme weather
39%
Late-arriving aircraft
36%
Carrier
19%
National Airspace System
6%

Extreme weather accounts for 39% 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 6.6 times the usual weather exposure. The split is drawn from 1,411 reported delay minutes.

36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,411 reported delay minutes here, that single category outweighs weather by 1 to one.

Cancellations sit at 1.59% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 88.5% on time across 126 flights, within 2 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. 126 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: treat all of this as provisional. 126 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 90.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 124 completed flights over 12 months sit behind that.
