What the record says about this route
The two directions do not behave alike. DTW to LAS arrives on time 13.5 points less often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.
This route does better than its own airport. Departures from LAS overall run 11 points less punctual than this particular one — so whatever congestion LAS has, this route is largely escaping it.
Only Delta Air Lines flies this route in the published record, so there is no choice to weigh — the route's figures and the airline's are the same figures.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on LAS to DTW during March 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
