Every carrier on PHL to BTV, 1,144 flights

These figures cover 126 flights between September 2025 and August 2026. The median arrival is 13 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Departure window

When Republic runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against half a point between the best and worst carrier.

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 2pm–5pm slot at 95.5% on time, ahead of 8pm–5am at 74.2%. 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 8am–11am window is the busiest, with 49 flights scheduled in it.

Delay causes

Why Republic runs late on this route

Late-arriving aircraft accounts for 71% of the 1,062 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    71%
  • Carrier
    24%
  • National Airspace System
    5%

71% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,062 reported delay minutes here, that single category outweighs weather by 71 to one. The split is drawn from 1,062 reported delay minutes.

Cancellations are rare at 0.79%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.5% 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 2pm–5pm window matters as much as it does.

The return leg runs 90.3% 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 PHL to BTV

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 88.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 122 completed flights over 12 months sit behind that.
