These figures cover 295 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
DL 910 quarter by quarter
Quarter by quarter DL 910 held fairly steady: 74.0% in Oct–Dec 2025, 79.5% in Jan–Mar 2026, 75.3% in Apr–Jun 2026 and 78.7% in Jul–Sep 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.

- Jan–Mar 202674 flights79.5%
- Apr–Jun 202674 flights75.3%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 910 did best on Thursday at 85.4% on time and worst on Sunday at 69.6%. Each day rests on about 42 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 290 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 48 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 21 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at TPA.
The worst days
Worst days for DL 910
The latest arrival of the period was on 16 June 2026, 9 hours 25 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 295 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. 295 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 910
