A 10:35 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 1747 runs 12 points worse at 72.2%. 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 1747 quarter by quarter
DL 1747 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.3% on time and its weakest Jul–Sep 2026 at 67.2%, a swing of 14 points on roughly 85 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.

- Jan–Mar 202690 flights69.7%
- Apr–Jun 202691 flights81.3%
- Jul–Sep 202662 flights67.2%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1747 did best on Monday at 80.6% on time and worst on Friday at 60.0%. Each day rests on about 36 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Share of 252 completed flights by arrival against schedule.
18 of 67 late departures made up the time and arrived on time, 27% of them. In the other direction, 21 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 MCO.
The worst days
Worst days for DL 1747
The latest arrival of the period was on 2 January 2026, 9 hours 44 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 January 2026 | 9 hours 44 minutes | Carrier |
| 27 June 2026 | 9 hours 38 minutes | Carrier |
| 10 March 2026 | 8 hours 14 minutes | Carrier |

Delay causes
Why DL 1747 runs late
Carrier accounts for 64% of the 5,504 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 22%National Airspace System
- 12%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,504 of the 5,504 delay minutes reported here. The split is drawn from 5,504 delay minutes reported on DL 1747.
Cancellations are rare at 0.39%, 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
10.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 957 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on five other city pairs in the data, including MCO to DTW (249), GRB to DTW (22) and DTW to GRB (22), but none flew often enough under DL 1747 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to MCO only.
One caution: this is a thin sample. 255 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 1747
For a booking, read DL 1747 as 72.2% on time with 0.39% cancelled over 255 flights. Those are rates from the past twelve months, not a forecast for any particular day.
