These figures cover 365 flights between September 2025 and August 2026. The median arrival is 13 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 worst days
Worst days for DL 2289
The latest arrival of the period was on 17 March 2026, 2 hours 30 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 March 2026 | 2 hours 30 minutes | Carrier |
| 5 December 2025 | 2 hours 29 minutes | National Airspace System |
| 21 September 2025 | 2 hours 2 minutes | Carrier |
| 12 May 2026 | 1 hour 19 minutes | Carrier |
| 2 August 2026 | 1 hour 7 minutes | National Airspace System |
Delay causes
Why DL 2289 runs late
Carrier accounts for 65% of the 1,070 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Carrier
- 35%National Airspace System
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 371 minutes out of 1,070, against a national NAS share of 21%. The split is drawn from 1,070 delay minutes reported on DL 2289.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 1.4% 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 1,481 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 2289 in the data flew SLC to DTW. 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 2289
For a booking, DL 2289 has one of the better records a US domestic flight can show: 93.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
