Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1495, check with Delta Air Lines.

DL 1495 sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 335 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1495 runs 4 points behind the country as a whole. Across a thousand flights that is about 44 extra late arrivals.

These figures cover 335 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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 DL 1495 flies

DL 1495 flies ATL to PBI without a single fixed slot. Its most common scheduled departure was 21:15, used on 67 of 335 flights, with 22:30 (38 flights) and 21:57 (37 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 21:15 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1495 runs 3 points better at 73.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 1495 quarter by quarter

DL 1495 did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.6% on time and its weakest Jan–Mar 2026 at 70.0%, a swing of 14 points on roughly 84 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 1495 did best on Wednesday at 85.7% on time and worst on Sunday at 59.6%. Each day rests on about 48 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1495 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 6,002 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

The largest share of delay minutes, 62%, 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 3,712 of the 6,002 delay minutes reported here. The split is drawn from 6,002 delay minutes reported on DL 1495.

Cancellations sit at 0.90% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

8.4% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 335 flights under DL 1495 in the data flew ATL to PBI. 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. 335 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 1495
