What the record says about this route
The shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 105 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.
Flights from Knoxville to Detroit are among the most dependable in the record. A route this punctual is usually a short hop between airports with slots to spare.
This route does better than its own airport. Departures from TYS overall run 14.4 points less punctual than this particular one — so whatever congestion TYS has, this route is largely escaping it.
The two directions do not behave alike. DTW to TYS arrives on time 7.4 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.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on TYS to DTW during July 2024 – July 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 →
