These figures cover 268 flights between September 2025 and August 2026. The median arrival is 12 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 F9 2059 runs late

Carrier accounts for 61% of the 3,233 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

Late-arriving aircraft
22%
National Airspace System
16%
Extreme weather

The largest share of delay minutes, 61%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,969 of the 3,233 delay minutes reported here. The split is drawn from 3,233 delay minutes reported on F9 2059.

Cancellations are rare at 0.75%, 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 routes

What a delay on this flight costs

5.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

Every one of the 268 flights under F9 2059 in the data flew PHL to RDU. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 268 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 F9 2059

For a booking, read F9 2059 as 83.5% on time with 0.75% cancelled over 268 flights. Those are rates from the past twelve months, not a forecast for any particular day.
