DL 749 lands a B, 2 points better than the national rate of 77.6%. About one flight in five 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 365 flights, with a median arrival 2 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 2 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 749 flies

DL 749 flies LAX to TPA without a single fixed slot. Its most common scheduled departure was 10:40, used on 42 of 365 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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 84.1%, and DL 749 runs 5 points worse at 79.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 749 next to LAX to TPA

Every carrier on LAX to TPA combined arrived on time 79.7% of the time across 1,191 flights, so DL 749 is about level with it. Delta flew 659 flights on the same city pair under all its flight numbers, including this one, and those ran 78.6% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 2 points.

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 90.1% on time and its weakest Oct–Dec 2025 at 67.0%, a swing of 23 points on roughly 91 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 202592 flights90.1%
Oct–Dec 202592 flights67.0%
Jan–Mar 202690 flights79.3%
Apr–Jun 202691 flights81.1%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 749 did best on Wednesday at 86.3% on time and worst on Friday at 70.0%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 749 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 4,185 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
46%
Late-arriving aircraft
29%
National Airspace System
25%

The largest share of delay minutes, 46%, 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 1,914 of the 4,185 delay minutes reported here. The split is drawn from 4,185 delay minutes reported on DL 749.

Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.8% 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 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 (242), 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 79.4% on time with 1.64% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
