These figures cover 334 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.

Schedule

When DL 1301 flies

DL 1301 is scheduled to leave West Palm Beach (PBI) at 08:00 local time and reach Atlanta (ATL) at 09:55. That slot held for 275 of the 334 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 1301 runs 7 points better at 91.0%. 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

DL 1301 quarter by quarter

DL 1301 did not run the same all year. Its best quarter was Jul–Sep 2025 at 100.0% on time and its weakest Jan–Mar 2026 at 87.8%, a swing of 12 points on roughly 67 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.

By weekday, DL 1301 did best on Wednesday at 100.0% on time and worst on Monday at 79.2%. Each day rests on about 48 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1301 runs late

Carrier accounts for 50% of the 2,567 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
27%
Extreme weather
17%
Late-arriving aircraft
5%

Extreme weather accounts for 17% 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 quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.9 times the usual weather exposure. The split is drawn from 2,567 delay minutes reported on DL 1301.

Cancellations are rare at 0.60%, 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

Badly late arrivals are rare here: only 3.6% 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 545 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.

Every one of the 334 flights under DL 1301 in the data flew PBI to ATL. 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. 334 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 DL 1301

For a booking, DL 1301 has one of the better records a US domestic flight can show: 91.0% on time and 0.60% cancelled. That is a base rate, not a promise about any single day.
