These figures cover 332 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.

- 60%Carrier

Connections and routes
What a delay on this flight costs
5.9% 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 roughly 50 minutes, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including STL to DTW (117) and LGA to BOS (16), but none flew often enough under DL 2822 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to STL only.
One caution: this is a thin sample. 332 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 2822
For a booking, read DL 2822 as 78.7% on time with 1.81% cancelled over 332 flights. Those are rates from the past twelve months, not a forecast for any particular day.
