Across the year
DL 1372 quarter by quarter

Share of 354 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 79 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 30 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 1372
The latest arrival of the period was on 2 May 2026, 4 hours 39 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.

| 16 March 2026 | 4 hours 28 minutes | Late-arriving aircraft |

Delay causes
Why DL 1372 runs late
National Airspace System accounts for 44% of the 5,686 delay minutes carriers reported here, and the remaining four split what is left.
- 44%National Airspace System
- 36%Carrier
- 19%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,059 of the 5,686 delay minutes reported here. The split is drawn from 5,686 delay minutes reported on DL 1372.
Cancellations are rare at 0.28%, 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
8.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
DL 1372 is not only a ATL to MCO flight. It also flew MCO to ATL (358 flights, 64.7% 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. 359 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.
