What stands out
How DL1370 compares to other flight numbers, not just to itself.
This flight's worst arrivals run unusually far past its typical one, a bigger gap than 97% of 11,788 comparable flight numbers.
A typical arrival is 5 min early, but the worst tenth run 116 minutes worse than that.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| DL1370 | 68.2% | 3.25% | -5 min | 16.6% | 616 |
| Delta Air Lines on MCO → RDU | 76.8% | 1.80% | -9 min | 10.5% | 2,996 |
| All MCO → RDU flights | 75.6% | 1.38% | -6 min | 10.4% | 8,429 |
DL1370 has cancelled 3.25% of its scheduled departures (20 of 616), against 1.38% for all MCO → RDU flights — this specific departure cancels 1.9 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about DL1370 specifically, not about the route it flies.

Why DL1370 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for DL1370 on MCO → RDU. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL1370 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL1370 pushed back an average of 94 minutes late; when it came in on time or early, an average of 2 minutes early.
Each departure is matched to the flight the same aircraft flew into MCO just before it, using the tail number in the DOT file, 579 of 596 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| DL1370 | 30% | 80% | 9% |
| Network, same turn | 18% | 85% | 10% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often DL1370’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often DL1370 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves MCO late, does that still matter by the time it reaches RDU?
DL1370 pushes back an average of 29.3 minutes late and reaches the gate at RDU an average of 23.8 minutes late. The 5.5 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. Its 17.7 minutes on the taxiways at MCO is about what any departure from the airport in that hour spends.
On arrival at RDU, DL1370 spends 7.7 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at RDU spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached RDU. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 28,369 departures from MCO scheduled in the clock hour DL1370 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at RDU (179,931 flights), not just DL1370’s own. More on taxi time.

The hour it leaves MCO
Part of any flight’s record belongs to the clock rather than to the flight. DL1370 has one departure time, so this is what that time is worth.
On-time arrival rate. 28,369 departures from MCO are scheduled in the 8 PM–9 PM hour over the period, against 498,221 across the whole day.
DL1370 is scheduled out of MCO at 8:59 PM, in the 8 PM–9 PM bank. Departures from MCO in that hour arrive on time 61.0% of the time against 74.8% across the airport’s whole day — the slot alone is worth 13.8 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from MCO to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Other routes DL1370 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| ATL→HPN Atlanta to White Plains | May 7, 2024 – June 6, 2024 | 31 | — |
| RDU→MCO Raleigh–Durham to Orlando | April 9, 2024 – May 6, 2024 | 28 | — |
| RDU→BOS Raleigh–Durham to Boston | July 3, 2023 – April 8, 2024 | 171 | 74.4% |
| DTW→DEN Detroit to Denver | January 8, 2024 – March 9, 2024 | 62 | — |
Because the same number has served different journeys, the statistics above describe only the route DL1370 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
111 min late
against a median of 5 min early
DL1370 has an average that understates its risk: a typical arrival is 5 min early, but the worst tenth are 116 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL1370 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 616 records of DL1370 operating MCO → RDU, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
