These figures cover 363 flights between September 2025 and August 2026. The median arrival is 7 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.

Worst days for DL 2244
The latest arrival of the period was on 11 March 2026, 3 hours 53 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 11 March 2026 | 3 hours 53 minutes | Carrier |
| 24 September 2025 | 3 hours 4 minutes | Carrier |
| 13 March 2026 | 2 hours 51 minutes | National Airspace System |

Delay causes
Why DL 2244 runs late
Carrier accounts for 62% of the 2,325 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 23%National Airspace System
- 14%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,442 of the 2,325 delay minutes reported here. The split is drawn from 2,325 delay minutes reported on DL 2244.
Cancellations are rare at 0.28%, below the national 1.89% 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 3.3% 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 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 363 flights under DL 2244 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. 363 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 2244
For a booking, DL 2244 has one of the better records a US domestic flight can show: 88.4% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
