Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1450, check with Delta Air Lines.

DL 1450 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 348 flights, with a median arrival 3 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1450 runs 5 points behind the country as a whole. Across a thousand flights that is about 53 extra late arrivals.

These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 10.5% 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 1450 flies

DL 1450 flies ATL to MSY without a single fixed slot. Its most common scheduled departure was 19:40, used on 88 of 348 flights, with 19:47 (61 flights) and 19:35 (50 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 19:40 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1450 runs 4 points better at 72.3%. 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 1450 quarter by quarter

DL 1450 did not run the same all year. Its best quarter was Apr–Jun 2026 at 80.2% on time and its weakest Jul–Sep 2025 at 60.9%, a swing of 19 points on roughly 87 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.

Jul–Sep 202592 flights60.9%
Oct–Dec 202579 flights71.4%
Jan–Mar 202686 flights77.1%

Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1450 did best on Wednesday at 86.0% on time and worst on Sunday at 57.4%. Each day rests on about 50 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1450 runs late

One category carries most of the weight here. Carrier accounts for 48% of the 6,203 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.

Late-arriving aircraft

0%

36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,203 reported delay minutes here, that single category outweighs weather by 13 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,203 delay minutes reported on DL 1450.

Cancellations sit at 1.44% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 10.5% 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.

The same number turns up on one other city pair in the data, including ATL to BHM (16), but none flew often enough under DL 1450 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MSY only.

One caution: this is a thin sample. 348 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 1450

For a booking, DL 1450 is one of the weaker ways to fly ATL to MSY: 9 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
