Historical statistics for July 2025 to June 2026, not live status. For today’s DL 446, check with Delta Air Lines.

DL 446 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 340 flights, with a median arrival 5 minutes early.

Set against the rest of the country, DL 446's record is 6 points better than the US average of 77.6%. That gap is worth roughly 59 fewer late arrivals for every thousand flights.

These figures cover 340 flights between July 2025 and June 2026. The median arrival is 5 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 446 flies

DL 446 flies LAX to ATL without a single fixed slot. Its most common scheduled departure was 12:10, used on 109 of 340 flights, with 12:20 (62 flights) and 12:45 (34 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 12:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 446 runs 5 points better at 83.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 446 next to LAX to ATL

Every carrier on LAX to ATL combined arrived on time 78.4% of the time across 5,013 flights, so DL 446 is 5 points ahead of it. Delta flew 3,844 flights on the same city pair under all its flight numbers, including this one, and those ran 81.5% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 2 points.

Across the year

DL 446 quarter by quarter

Quarter by quarter DL 446 held fairly steady: 80.2% in Jul–Sep 2025, 85.9% in Oct–Dec 2025, 85.5% in Jan–Mar 2026 and 82.4% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202584 flights80.2%
Oct–Dec 202580 flights85.9%
Jan–Mar 202685 flights85.5%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 446 did best on Sunday at 91.7% on time and worst on Friday at 76.1%. Each day rests on about 49 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 446 runs late

One category carries most of the weight here. Carrier accounts for 54% of the 4,342 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.

Carrier
54%
Late-arriving aircraft
29%
National Airspace System
17%

The largest share of delay minutes, 54%, 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 2,330 of the 4,342 delay minutes reported here. The split is drawn from 4,342 delay minutes reported on DL 446.

Cancellations sit at 1.47% against a national 1.81%, which is ordinary. Diversions add another 0.59%.

Connections and routes

What a delay on this flight costs

6.0% 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 a little over an hour, which a normal layover absorbs.

At 1,947 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on one other city pair in the data, including MIA to BOS (16), but none flew often enough under DL 446 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to ATL only.

One caution: this is a thin sample. 340 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 446

For a booking, read DL 446 as 83.5% on time with 1.47% cancelled over 340 flights. Those are rates from the past twelve months, not a forecast for any particular day.
