DL 910 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 294 flights, with a median arrival 3 minutes early.

These figures cover 294 flights between July 2025 and June 2026. The median arrival is 3 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 910 flies

DL 910 flies LAX to TPA without a single fixed slot. Its most common scheduled departure was 22:20, used on 60 of 294 flights, with 22:37 (50 flights) and 22:15 (48 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 22:20 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 910 runs 7 points better at 77.6%. 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 910 quarter by quarter

Quarter by quarter DL 910 held fairly steady: 81.7% in Jul–Sep 2025, 74.0% in Oct–Dec 2025, 79.5% in Jan–Mar 2026 and 75.3% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202674 flights79.5%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 910 ranged from 73.5% on Friday to 83.0% on Thursday. With about 42 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 910 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 3,677 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, 55%, 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 2,016 of the 3,677 delay minutes reported here. The split is drawn from 3,677 delay minutes reported on DL 910.

Cancellations sit at 1.36% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.5% 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.

At 2,158 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.

Every one of the 294 flights under DL 910 in the data flew LAX to TPA. 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. 294 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.
