These figures cover 363 flights between July 2025 and June 2026. Beyond the headline rate, 12.9% 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 1150 flies

DL 1150 flies ATL to MCO without a single fixed slot. Its most common scheduled departure was 14:50, used on 88 of 363 flights, with 14:59 (63 flights) and 14:55 (62 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 14:50 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1150 runs 8 points worse at 64.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1150 quarter by quarter

DL 1150 did not run the same all year. Its best quarter was Oct–Dec 2025 at 72.2% on time and its weakest Jan–Mar 2026 at 60.9%, a swing of 11 points on roughly 91 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 1150 did best on Wednesday at 74.5% on time and worst on Saturday at 54.9%. Each day rests on about 52 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1150 runs late

One category carries most of the weight here. Carrier accounts for 45% of the 7,870 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.

  • Carrier
    45%
  • National Airspace System
    37%
  • Late-arriving aircraft
    16%
  • Extreme weather
    1%

37% 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 2,903 minutes out of 7,870, against a national NAS share of 21%. The split is drawn from 7,870 delay minutes reported on DL 1150.

Cancellations are rare at 0.83%, below the national 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.9% 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.

DL 1150 is not only a ATL to MCO flight. It also flew MCO to ATL (363 flights, 60.7% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 363 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 1150

For a booking, DL 1150 is a flight to put a long connection behind. 12.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
