These figures cover 365 flights between September 2025 and August 2026. The median arrival is 11 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.

A 07:20 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2922 runs level with that at 91.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why DL 2922 runs late
Carrier accounts for 62% of the 1,940 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 31%National Airspace System
- 7%Late-arriving aircraft
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,207 of the 1,940 delay minutes reported here. The split is drawn from 1,940 delay minutes reported on DL 2922.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.3% 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 867 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 one other city pair in the data, including LAS to SEA (239), but none flew often enough under DL 2922 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to LAS only.
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 2922
For a booking, DL 2922 has one of the better records a US domestic flight can show: 91.1% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
