These figures cover 365 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:40 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 749 runs 5 points worse at 79.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 749 quarter by quarter
DL 749 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Oct–Dec 2025 at 67.0%, a swing of 30 points on roughly 73 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.
- Jul–Sep 202530 flights96.7%
- Oct–Dec 202592 flights67.0%
- Jan–Mar 202690 flights79.3%
- Apr–Jun 202691 flights81.1%
- Jul–Sep 202662 flights85.2%
Scale runs 60% to 100%.
By weekday, DL 749 did best on Thursday at 86.5% on time and worst on Sunday at 70.6%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 359 completed flights by arrival against schedule.
8 of 48 late departures made up the time and arrived on time, 17% of them. In the other direction, 35 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.

Delay causes
Why DL 749 runs late
Carrier accounts for 48% of the 4,247 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 27%Late-arriving aircraft
- 25%National Airspace System
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,036 of the 4,247 delay minutes reported here. The split is drawn from 4,247 delay minutes reported on DL 749.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
5.6% of arrivals land an hour or more late, close to the national 8.3%, so 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.
The same number turns up on one other city pair in the data, including TPA to LAX (243), but none flew often enough under DL 749 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to TPA only.
One caution: this is a thin sample. 365 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 749
For a booking, read DL 749 as 79.1% on time with 1.37% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
