DL 1457 draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 360 flights, with a median arrival 1 minute early.

These figures cover 360 flights between July 2025 and June 2026. Beyond the headline rate, 12.7% 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 1457 flies

DL 1457 flies ATL to TPA without a single fixed slot. Its most common scheduled departure was 19:30, used on 57 of 360 flights, with 18:20 (45 flights) and 19:56 (39 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 19:30 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1457 runs level with that at 67.5%. 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 1457 quarter by quarter

DL 1457 did not run the same all year. Its best quarter was Jan–Mar 2026 at 72.1% on time and its weakest Jul–Sep 2025 at 57.6%, a swing of 14 points on roughly 90 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.

Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1457 did best on Wednesday at 78.0% on time and worst on Sunday at 52.9%. Each day rests on about 51 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1457 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 7,207 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.

Extreme weather
10%

The largest share of delay minutes, 46%, 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 3,325 of the 7,207 delay minutes reported here. The split is drawn from 7,207 delay minutes reported on DL 1457.

Cancellations sit at 1.67% 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. 12.7% 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 TPA to ATL (38), but none flew often enough under DL 1457 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to TPA only.

One caution: this is a thin sample. 360 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 1457

For a booking, DL 1457 is a flight to put a long connection behind. 12.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
