Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2309, check with Delta Air Lines.

DL 2309 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 353 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so DL 2309 runs 8 points behind the country as a whole. Across a thousand flights that is about 77 extra late arrivals.

These figures cover 353 flights between July 2025 and June 2026. Beyond the headline rate, 11.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 2309 flies

DL 2309 flies MSP to MCO without a single fixed slot. Its most common scheduled departure was 19:45, used on 102 of 353 flights, with 18:45 (87 flights) and 19:59 (38 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 19:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2309 runs level with that at 69.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 2309 quarter by quarter

DL 2309 did not run the same all year. Its best quarter was Jan–Mar 2026 at 77.5% on time and its weakest Apr–Jun 2026 at 62.9%, a swing of 15 points on roughly 88 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.

By weekday, DL 2309 did best on Tuesday at 78.0% on time and worst on Sunday at 55.1%. Each day rests on about 50 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2309 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 7,305 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.

Late-arriving aircraft
25%
Extreme weather
15%
National Airspace System
13%

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 7,305 delay minutes reported on DL 2309.

Cancellations sit at 1.42% against a national 1.81%, which is ordinary. Diversions add another 0.57%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

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.

Every one of the 353 flights under DL 2309 in the data flew MSP 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. 353 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
