These figures cover 365 flights between September 2025 and August 2026. The median arrival is 12 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 largest share of delay minutes, 93%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,978 of the 4,259 delay minutes reported here. The split is drawn from 4,259 delay minutes reported on DL 2290.

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 close to two hours, which a normal layover absorbs.
The 1,262 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.
Every one of the 365 flights under DL 2290 in the data flew MEM to SLC. The number was not reused on any other city pair, which makes this a clean record of one route.
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 2290
For a booking, DL 2290 has one of the better records a US domestic flight can show: 90.3% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
