How DL710 performs
681 operations, June 2024 – July 2026.
DL710 arrived on time 60.9% of the time, against 76.6% for all LGA → DEN flights, so this departure is 15.7 percentage points worse than the route as a whole. Against Delta Air Lines’ own flights on this route it is 15.8 points worse.

What stands out
How DL710 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 0 min early, but the worst tenth run 115 minutes worse than that.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| DL710 | 60.9% | 4.41% | 0 min | 20.3% | 681 |
| Delta Air Lines on LGA → DEN | 76.7% | 2.58% | -10 min | 9.8% | 3,174 |
| All LGA → DEN flights | 76.6% | 2.08% | -8 min | 8.9% | 14,618 |
DL710 has cancelled 4.41% of its scheduled departures (30 of 681), against 2.08% for all LGA → DEN flights — this specific departure cancels 2.3 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 DL710 specifically, not about the route it flies.

Why DL710 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies DL710 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL710 pushed back an average of 74 minutes late; when it came in on time or early, an average of 7 minutes late.
Each departure is matched to the flight the same aircraft flew into LGA just before it, using the tail number in the DOT file, 601 of 656 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 |
|---|---|---|---|
| DL710 | 23% | 81% | 17% |
| Network, same turn | 17% | 68% | 9% |
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 60 to 89 minutes. How often DL710’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often DL710 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves LGA late, does that still matter by the time it reaches DEN?
DL710 pushes back an average of 32.6 minutes late and reaches the gate at DEN an average of 26.0 minutes late. The 6.6 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. It spends 27.9 minutes on the taxiways at LGA, 1.9 minutes longer than a typical LGA departure in the same hour.
On arrival at DEN, DL710 spends 10.2 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 DEN 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 DEN. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 29,293 departures from LGA scheduled in the clock hour DL710 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DEN (963,027 flights), not just DL710’s own. More on taxi time.

The hour it leaves LGA
Part of any flight’s record belongs to the clock rather than to the flight. DL710 has one departure time, so this is what that time is worth.
On-time arrival rate. 29,293 departures from LGA are scheduled in the 6 PM–7 PM hour over the period, against 456,467 across the whole day.
DL710 is scheduled out of LGA at 6:00 PM, in the 6 PM–7 PM bank. Departures from LGA in that hour arrive on time 69.5% of the time against 78.3% across the airport’s whole day — the slot alone is worth 8.8 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from LGA 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 DL710 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.

Because the same number has served different journeys, the statistics above describe only the route DL710 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.
115 min late
against a median of 0 min early
DL710 has an average that understates its risk: a typical arrival is 0 min early, but the worst tenth are 115 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| DL751 | Delta Air Lines | 85.0% | 10 min early | 782 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL710 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 681 records of DL710 operating LGA → DEN, 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.
