These figures cover 314 flights between September 2025 and August 2026. The median arrival is 6 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.

Across the year
DL 2442 quarter by quarter
DL 2442 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.7% on time and its weakest Oct–Dec 2025 at 73.9%, a swing of 12 points on roughly 79 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.

By weekday, DL 2442 did best on Friday at 86.4% on time and worst on Monday at 68.1%. Each day rests on about 45 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 2442
The latest arrival of the period was on 5 November 2025, 3 hours 58 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 November 2025 | 3 hours 58 minutes | National Airspace System |
| 10 November 2025 | 3 hours 12 minutes | Carrier |
| 12 December 2025 | 3 hours | Carrier |

Delay causes
Why DL 2442 runs late
Carrier accounts for 43% of the 3,334 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Carrier
- 33%National Airspace System
- 23%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,445 of the 3,334 delay minutes reported here. The split is drawn from 3,334 delay minutes reported on DL 2442.
Cancellations are rare at 0.64%, 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
6.1% 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 about 55 minutes, which a normal layover absorbs.
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.
The same number turns up on two other city pairs in the data, including PHX to SEA (181) and RIC to ATL (24), but none flew often enough under DL 2442 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to PHX only.
One caution: this is a thin sample. 314 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 2442
For a booking, read DL 2442 as 80.4% on time with 0.64% cancelled over 314 flights. Those are rates from the past twelve months, not a forecast for any particular day.
