These figures cover 365 flights between September 2025 and August 2026. The median arrival is 15 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.

The worst days
Worst days for DL 2419
The latest arrival of the period was on 31 March 2026, 5 hours 6 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 31 March 2026 | 5 hours 6 minutes | Late-arriving aircraft |
| 8 December 2025 | 3 hours 50 minutes | Late-arriving aircraft |
| 10 November 2025 | 1 hour 10 minutes | Late-arriving aircraft |
| 2 August 2026 | 1 hour 8 minutes | Late-arriving aircraft |
| 12 October 2025 | 1 hour 7 minutes | Late-arriving aircraft |
Delay causes
Why DL 2419 runs late
Late-arriving aircraft accounts for 75% of the 1,264 delay minutes carriers reported here, and the remaining four split what is left.
- 75%Late-arriving aircraft
- 16%National Airspace System
- 9%Carrier
75% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,264 reported delay minutes here, that single category outweighs weather by 75 to one. The split is drawn from 1,264 delay minutes reported on DL 2419.
Cancellations are rare at 0.55%, below the national 1.89% 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 1.4% land an hour or more behind schedule, against 8.3% 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.
DL 2419 is not only a PHX to SEA flight. It also flew SEA to PHX (365 flights, 89.8% 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.
| Also flown as | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| SEA to PHX | 365 | 89.8% | 53 min | 0.27% | A+ |
What to do with this
Booking DL 2419
