DL 2442 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 314 flights, with a median arrival 7 minutes early.

These figures cover 314 flights between July 2025 and June 2026. The median arrival is 7 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 2442 flies

DL 2442 flies SEA to PHX without a single fixed slot. Its most common scheduled departure was 15:25, used on 51 of 314 flights, with 13:30 (45 flights) and 15:20 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 15:25 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2442 runs 8 points better at 80.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 2442 next to SEA to PHX

Every carrier on SEA to PHX combined arrived on time 79.2% of the time across 7,268 flights, so DL 2442 is about level with it. Delta flew 1,765 flights on the same city pair under all its flight numbers, including this one, and those ran 82.6% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 2 points.

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 Tuesday at 86.4% on time and worst on Monday at 66.7%. Each day rests on about 45 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2442 runs late

One category carries most of the weight here. Carrier accounts for 48% of the 3,647 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.

Carrier
48%
National Airspace System
28%
Late-arriving aircraft
25%

The largest share of delay minutes, 48%, 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 1,744 of the 3,647 delay minutes reported here. The split is drawn from 3,647 delay minutes reported on DL 2442.

Cancellations are rare at 0.64%, 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

7.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, 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. 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.

The same number turns up on two other city pairs in the data, including PHX to SEA (159) 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 80.0% on time with 0.64% cancelled over 314 flights. Those are rates from the past twelve months, not a forecast for any particular day.
