Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1730, check with Delta Air Lines.

DL 1730 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 253 flights, with a median arrival 11 minutes early.

Set against the rest of the country, DL 1730's record is 12 points better than the US average of 77.6%. That gap is worth roughly 124 fewer late arrivals for every thousand flights.

These figures cover 253 flights between July 2025 and June 2026. The median arrival is 11 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 1730 flies

DL 1730 flies MCO to MSP without a single fixed slot. Its most common scheduled departure was 07:50, used on 56 of 253 flights, with 11:25 (35 flights) and 12:15 (32 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 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 90.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1730 next to MCO to MSP

Every carrier on MCO to MSP combined arrived on time 77.6% of the time across 1,942 flights, so DL 1730 is 12 points ahead of it. Delta flew 1,868 flights on the same city pair under all its flight numbers, including this one, and those ran 77.5% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 8 points.

Across the year

DL 1730 quarter by quarter

Quarter by quarter DL 1730 held fairly steady: 87.0% in Jul–Sep 2025, 91.4% in Jan–Mar 2026 and 93.2% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights87.0%

By weekday, DL 1730 did best on Tuesday at 94.3% on time and worst on Saturday at 81.1%. Each day rests on about 36 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

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 1,097 reported delay minutes.

National Airspace System
32%
Carrier
32%
Late-arriving aircraft
30%
Extreme weather
6%

32% 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 351 minutes out of 1,097, against a national NAS share of 21%. The split is drawn from 1,097 delay minutes reported on DL 1730.

Cancellations sit at 1.58% against a national 1.81%, 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 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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

For a booking, read DL 1730 as 90.0% on time with 1.58% cancelled over 253 flights. Those are rates from the past twelve months, not a forecast for any particular day.
