DL 2419 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 365 flights, with a median arrival 13 minutes early.
Set against the rest of the country, DL 2419's record is 14 points better than the US average of 77.6%. That gap is worth roughly 144 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 13 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 DL 2419 flies
DL 2419 flies SEA to PHX without a single fixed slot. Its most common scheduled departure was 07:10, used on 166 of 365 flights, with 07:20 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:10 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2419 runs 3 points better at 92.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
DL 2419 next to SEA to PHX

Across the year
DL 2419 quarter by quarter
DL 2419 did not run the same all year. Its best quarter was Jul–Sep 2025 at 98.9% on time and its weakest Oct–Dec 2025 at 85.7%, a swing of 13 points on roughly 91 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.
- Jul–Sep 202592 flights98.9%
- Oct–Dec 202592 flights85.7%
- Jan–Mar 202690 flights90.0%
- Apr–Jun 202691 flights93.4%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2419 ranged from 86.5% on Tuesday to 98.1% on Sunday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 2419 runs late
One category carries most of the weight here. Carrier accounts for 56% of the 1,765 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 56%Carrier
- 36%National Airspace System
- 7%Extreme weather
- 1%Late-arriving aircraft
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 986 of the 1,765 delay minutes reported here. The split is drawn from 1,765 delay minutes reported on DL 2419.
Cancellations are rare at 0.27%, below the national 1.81% 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
Badly late arrivals are rare here: only 2.2% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 1,107 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
DL 2419 is not only a SEA to PHX flight. It also flew PHX to SEA (365 flights, 92.8% 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. 365 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
Booking DL 2419
For a booking, DL 2419 has one of the better records a US domestic flight can show: 92.0% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
