These figures cover 217 flights between September 2025 and August 2026. The median arrival is 10 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.

Delay causes
Why Republic runs late on this route
Carrier accounts for 64% of the 1,821 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 23%Late-arriving aircraft
- 9%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,157 of the 1,821 delay minutes reported here. The split is drawn from 1,821 reported delay minutes.
Cancellations sit at 1.38% against a national 1.89%, which is ordinary. Diversions add another 0.46%.
Connections and stage length
What a delay here costs
5.6% 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 about an hour, which a normal layover absorbs.
At 296 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 82.2% on time across 217 flights, 4 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.
One caution: this is a thin sample. 217 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 Republic on DTW to LEX
Put together: treat all of this as provisional. 217 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 86.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 213 completed flights over 12 months sit behind that.
