UA1406
Washington (IAD) to Fort Myers (RSW) · scheduled 9:00 AM – 11:26 AM
How UA1406 performs
991 operations, July 2023 – July 2026.
UA1406 arrived on time 88.1% of the time, against 85.9% for all IAD → RSW flights, so this departure is 2.2 percentage points better than the route as a whole. Against United Airlines’ own flights on this route it is 2.2 points better.
UA1406’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 9:00 AM earlier on, and around 8:15 AM more recently — a 45-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Why UA1406 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for UA1406 on IAD → RSW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1406 comes in late, and what that does to the departure.
The aircraft flying UA1406 came in 15 or more minutes late on 16% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into IAD just before it, using the tail number in the DOT file, 754 of 980 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 |
|---|---|
| UA1406 | 16% |
| Network, same turn | 23% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often UA1406’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves IAD late, does that still matter by the time it reaches RSW?
UA1406 pushes back an average of 2.0 minutes late and reaches the gate at RSW an average of 1.4 minutes early. The 3.3 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 20.6 minutes on the taxiways at IAD, 1.0 minutes longer than a typical IAD departure in the same hour.
On arrival at RSW, UA1406 spends 5.3 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 RSW 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 RSW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 7,688 departures from IAD scheduled in the clock hour UA1406 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at RSW (107,489 flights), not just UA1406’s own. More on taxi time.

The hour it leaves IAD
Part of any flight’s record belongs to the clock rather than to the flight. UA1406 has one departure time, so this is what that time is worth.
On-time arrival rate. 7,688 departures from IAD are scheduled in the 9 AM–10 AM hour over the period, against 170,208 across the whole day.
UA1406 is scheduled out of IAD at 9:00 AM, in the 9 AM–10 AM bank. Departures from IAD in that hour arrive on time 87.6% of the time against 81.0% across the airport’s whole day — the slot alone is worth 6.7 points better before anything about this particular flight is considered.
The two airport figures cover every departure from IAD 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.

By day of week
Does UA1406 run worse on particular days?
Tuesday is historically the most reliable day and Monday the least, a gap of 8.2 percentage points.

Other routes UA1406 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 |
|---|---|---|---|
| EWR→ORD Newark to Chicago | May 20, 2026 | 1 | — |
| ORD→SFO Chicago to San Francisco | October 26, 2025 – December 17, 2025 | 53 | — |
| SFO→BOI San Francisco to Boise | October 26, 2025 – December 1, 2025 | 37 | — |
| CLE→SFO Cleveland to San Francisco | September 25, 2025 – October 25, 2025 | 31 | — |
| IAH→MFE Houston to McAllen | August 19, 2025 – September 24, 2025 | 37 | — |
Because the same number has served different journeys, the statistics above describe only the route UA1406 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 991 records of UA1406 operating IAD → RSW, 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.
