Historical statistics for July 2025 to June 2026, not live status. For today’s DL 922, check with Delta Air Lines.
DL 922 lands a B+, 3 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 50 minutes on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 5 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 5 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 922 flies
DL 922 flies SEA to ANC without a single fixed slot. Its most common scheduled departure was 10:45, used on 79 of 365 flights, with 09:35 (60 flights) and 10:25 (58 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 10:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 922 runs 4 points worse at 80.1%. 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
DL 922 quarter by quarter
DL 922 did not run the same all year. Its best quarter was Jul–Sep 2025 at 87.0% on time and its weakest Oct–Dec 2025 at 75.8%, a swing of 11 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 flights87.0%
- Oct–Dec 202592 flights75.8%
- Jan–Mar 202690 flights75.9%
- Apr–Jun 202691 flights81.3%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 922 did best on Saturday at 90.2% on time and worst on Thursday at 73.1%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 922 runs late
One category carries most of the weight here. Carrier accounts for 49% of the 3,527 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.
- 49%Carrier
- 35%National Airspace System
- 9%Late-arriving aircraft
- 7%Extreme weather
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,242 minutes out of 3,527, against a national NAS share of 21%. The split is drawn from 3,527 delay minutes reported on DL 922.
Cancellations are rare at 0.82%, 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 3.6% 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 1,448 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 922 is not only a SEA to ANC flight. It also flew ANC to SEA (365 flights, 88.6% 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.
