Historical statistics for July 2025 to June 2026, not live status. For today’s DL 622, check with Delta Air Lines.

DL 622 lands a B+, about a point worse than the national rate of 77.6%. About one flight in four 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 344 flights, with a median arrival 7 minutes early.

These figures cover 344 flights between July 2025 and June 2026. Beyond the headline rate, 8.8% 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 622 flies

DL 622 flies LAX to AUS without a single fixed slot. Its most common scheduled departure was 16:20, used on 72 of 344 flights, with 13:10 (43 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 16:20 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 622 runs 4 points better at 76.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 622 quarter by quarter

Quarter by quarter DL 622 held fairly steady: 78.3% in Jul–Sep 2025, 74.4% in Oct–Dec 2025, 77.6% in Jan–Mar 2026 and 76.9% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202679 flights77.6%

By weekday, DL 622 did best on Wednesday at 87.8% on time and worst on Saturday at 64.1%. Each day rests on about 49 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 622 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 5,571 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
2%

48% 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 5,571 reported delay minutes here, that single category outweighs weather by 24 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 5,571 delay minutes reported on DL 622.

Cancellations are rare at 0.87%, below the national 1.81% 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

8.8% 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.

The 1,242 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.

The same number turns up on one other city pair in the data, including AUS to LAX (43), but none flew often enough under DL 622 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to AUS only.

One caution: this is a thin sample. 344 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 622

For a booking, read DL 622 as 76.8% on time with 0.87% cancelled over 344 flights. Those are rates from the past twelve months, not a forecast for any particular day.
