Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2056, check with Delta Air Lines.

DL 2056 lands a B+, 3 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 4 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 4 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 2056 flies

DL 2056 flies SLC to MCO without a single fixed slot. Its most common scheduled departure was 17:35, used on 89 of 365 flights, with 17:30 (69 flights) and 17:10 (56 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 17:35 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2056 runs 12 points better at 80.4%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 2056 next to SLC to MCO

Every carrier on SLC to MCO combined arrived on time 82.4% of the time across 1,530 flights, so DL 2056 is 2 points behind it. Delta flew 1,415 flights on the same city pair under all its flight numbers, including this one, and those ran 82.9% on time. Across its whole network Delta Air Lines managed 81.6%, close to this flight's figure.

Across the year

DL 2056 quarter by quarter

Quarter by quarter DL 2056 held fairly steady: 73.6% in Jul–Sep 2025, 81.5% in Oct–Dec 2025, 83.1% in Jan–Mar 2026 and 83.3% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights73.6%
Oct–Dec 202592 flights81.5%
Jan–Mar 202690 flights83.1%
Apr–Jun 202691 flights83.3%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2056 ranged from 78.8% on Thursday to 82.4% on Sunday. With about 52 flights behind each day, a spread of 4 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2056 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 4,949 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.

3%

46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,949 reported delay minutes here, that single category outweighs weather by 17 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,949 delay minutes reported on DL 2056.

Cancellations are rare at 0.55%, below the national 1.81% 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

7.7% 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 a little over an hour, which a normal layover absorbs.

At 1,931 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 365 flights under DL 2056 in the data flew SLC to MCO. 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. 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 2056

For a booking, read DL 2056 as 80.4% on time with 0.55% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
