These figures cover 292 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule
When AS 419 flies
AS 419 flies MCO to SEA without a single fixed slot. Its most common scheduled departure was 09:00, used on 78 of 292 flights, with 16:52 (70 flights) and 16:43 (34 flights) next.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AS 419 runs 6 points worse at 77.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
AS 419 quarter by quarter
AS 419 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Jul–Sep 2026 at 66.7%, a swing of 17 points on roughly 58 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.

Scale runs 60% to 90%.
By weekday, AS 419 did best on Thursday at 87.5% on time and worst on Saturday at 65.9%. Each day rests on about 42 flights, so a gap of 22 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 419 runs when it is late
AS 419 often beats the schedule: 112 of 287 completed flights, 39%, arrived 15 minutes or more early. The 64 late arrivals split 22 under half an hour, 21 between 30 and 60 minutes, and 21 an hour or more.

Share of 287 completed flights by arrival against schedule.
14 of 63 late departures made up the time and arrived on time, 22% of them. In the other direction, 15 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 SEA.
The worst days
Worst days for AS 419
The latest arrival of the period was on 28 December 2025, 12 hours 38 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 December 2025 | 12 hours 38 minutes | Carrier |
| 26 August 2026 | 4 hours 53 minutes | Late-arriving aircraft |
| 13 March 2026 | 4 hours 35 minutes | Late-arriving aircraft |
| 14 August 2026 | 3 hours 40 minutes | Late-arriving aircraft |
| 22 February 2026 | 2 hours 56 minutes | Carrier |
Delay causes
Why AS 419 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,903 reported delay minutes.
- 40%Late-arriving aircraft
- 30%Carrier
- 18%National Airspace System
- 12%Extreme weather
Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 4,903 delay minutes reported on AS 419.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.34%.
Connections and routes
What a delay on this flight costs
7.3% 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 a little over an hour, which a normal layover absorbs.
At 2,554 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 292 flights under AS 419 in the data flew MCO to SEA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 292 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
