These figures cover 128 flights between September 2025 and August 2026. The median arrival is 11 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.

Delay causes

Why Republic runs late on this route

Late-arriving aircraft accounts for 50% of the 712 delay minutes carriers reported here, and the remaining four split what is left.

36%
Extreme weather

Extreme weather accounts for 12% 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 2.0 times the usual weather exposure. The split is drawn from 712 reported delay minutes.

50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 712 reported delay minutes here, that single category outweighs weather by 4 to one.

Cancellations are rare at 0.78%, 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 3.1% 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.

The 507 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.

The return leg is a different operation and performs like one: it runs 94.5% on time across 128 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. 128 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 CVG to PHL

Put together: treat all of this as provisional. 128 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 91.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 127 completed flights over 12 months sit behind that.
