Across the year

DL 745 quarter by quarter

DL 745 did not run the same all year. Its best quarter was Oct–Dec 2025 at 81.5% on time and its weakest Jan–Mar 2026 at 66.3%, a swing of 15 points on roughly 67 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.

By weekday, DL 745 did best on Wednesday at 91.7% on time and worst on Saturday at 63.8%. Each day rests on about 48 flights, so a gap of 28 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 745 runs when it is late

DL 745 often beats the schedule: 90 of 333 completed flights, 27%, arrived 15 minutes or more early. The 85 late arrivals split 31 under half an hour, 26 between 30 and 60 minutes, and 28 an hour or more.

Share of 333 completed flights by arrival against schedule.

21 of 88 late departures made up the time and arrived on time, 24% of them. In the other direction, 18 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 SLC.

The worst days

Worst days for DL 745

The latest arrival of the period was on 26 December 2025, 13 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

Delay causes

Why DL 745 runs late

Carrier accounts for 55% of the 6,437 delay minutes carriers reported here, and the remaining four split what is left.

The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,513 of the 6,437 delay minutes reported here. The split is drawn from 6,437 delay minutes reported on DL 745.

Cancellations are rare at 0.30%, below the national 1.89% 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

8.4% 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 a little over an hour, which a normal layover absorbs.

At 2,084 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.

DL 745 is not only a FLL to SLC flight. It also flew SLC to FLL (256 flights, 80.8% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 334 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.
