DL 2025 earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.3%. When something does go wrong the average delay runs a little over an hour. That rests on 349 flights, with a median arrival 10 minutes early.
Set against the rest of the country, DL 2025's record is 16 points better than the US average of 77.3%. That gap is worth roughly 163 fewer late arrivals for every thousand flights.

These figures cover 349 flights between September 2025 and August 2026. The median arrival is 10 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 2025 flies
DL 2025 flies MCO to SLC without a single fixed slot. Its most common scheduled departure was 07:00, used on 120 of 349 flights, with 07:10 (85 flights) and 07:15 (56 flights) next.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2025 runs 4 points better at 93.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

- Oct–Dec 202580 flights93.8%
- Jan–Mar 202686 flights94.1%

By weekday, DL 2025 ranged from 90.0% on Monday to 98.0% on Thursday. With about 50 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

The worst days
Worst days for DL 2025
The latest arrival of the period was on 23 November 2025, 10 hours 43 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.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 November 2025 | 10 hours 43 minutes | Carrier |
| 13 January 2026 | 3 hours 44 minutes | Carrier |
| 17 October 2025 | 3 hours 25 minutes | Carrier |
| 8 December 2025 | 1 hour 17 minutes | Late-arriving aircraft |
| 2 May 2026 | 1 hour 16 minutes | National Airspace System |
Delay causes
Why DL 2025 runs late
Carrier accounts for 72% of the 1,767 delay minutes carriers reported here, and the remaining four split what is left.
- 72%Carrier
- 18%Late-arriving aircraft
- 8%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 72%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,272 of the 1,767 delay minutes reported here. The split is drawn from 1,767 delay minutes reported on DL 2025.
Cancellations are rare at 0.86%, 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
Badly late arrivals are rare here: only 1.4% 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 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.
The same number turns up on one other city pair in the data, including EWR to ATL (16), but none flew often enough under DL 2025 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCO to SLC only.
One caution: this is a thin sample. 349 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 2025
For a booking, DL 2025 has one of the better records a US domestic flight can show: 93.6% on time and 0.86% cancelled. That is a base rate, not a promise about any single day.
