F9 2387 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average.

These figures cover 289 flights between July 2025 and June 2026. Beyond the headline rate, 10.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When F9 2387 flies

F9 2387 flies PHL to CLT without a single fixed slot. Its most common scheduled departure was 06:00, used on 66 of 289 flights, with 07:20 (54 flights) and 06:10 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 2387 runs 9 points worse at 80.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

F9 2387 quarter by quarter

F9 2387 did not run the same all year. Its best quarter was Apr–Jun 2026 at 85.5% on time and its weakest Jan–Mar 2026 at 72.9%, a swing of 13 points on roughly 72 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jan–Mar 202661 flights72.9%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, F9 2387 did best on Tuesday at 90.0% on time and worst on Sunday at 76.1%. Each day rests on about 41 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 2387 runs late

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 4,520 reported delay minutes.

Carrier
41%
Late-arriving aircraft
29%
National Airspace System
25%
Extreme weather
5%

The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,837 of the 4,520 delay minutes reported here. The split is drawn from 4,520 delay minutes reported on F9 2387.

Cancellations are rare at 0.69%, below the national 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

Every one of the 289 flights under F9 2387 in the data flew PHL to CLT. 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. 289 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 2387
