These figures cover 253 flights between September 2025 and August 2026. The median arrival is 12 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:50 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1730 runs level with that at 91.1%. 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 1730 quarter by quarter
DL 1730 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jul–Sep 2026 at 86.7%, a swing of 10 points on roughly 63 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 202530 flights96.7%
- Oct–Dec 202517 flights—
- Jan–Mar 202684 flights91.4%
- Apr–Jun 202660 flights93.2%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1730 ranged from 86.1% on Friday to 97.1% on Tuesday. With about 36 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 December 2025 | 2 hours | Late-arriving aircraft |
| 7 January 2026 | 1 hour 55 minutes | Carrier |
| 11 July 2026 | 1 hour 11 minutes | Carrier |

Delay causes
Why DL 1730 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 932 reported delay minutes.
- 36%National Airspace System
- 34%Carrier
- 23%Late-arriving aircraft
- 8%Extreme weather
36% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 331 minutes out of 932, against a national NAS share of 21%. The split is drawn from 932 delay minutes reported on DL 1730.
Cancellations sit at 2.37% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.2% 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.
The 1,310 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 one other city pair in the data, including MSP to MCO (196), but none flew often enough under DL 1730 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCO to MSP only.
One caution: this is a thin sample. 253 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 1730
