Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.

Republic on LEX to DTW lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 265 flights, with a median arrival 7 minutes early.

Set against the rest of the country, Republic's LEX to DTW record is 5 points better than the US average of 77.6%. That gap is worth roughly 45 fewer late arrivals for every thousand flights.

Every carrier on LEX to DTW, 786 flights

These figures cover 265 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Departure window

When Republic runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 265 flights.

There are not enough flights in each departure window to split Republic's LEX to DTW record by time of day without the percentages moving on noise. The headline rate of 82.1% is the reliable figure here.

Across the year

Republic on LEX to DTW through the year

Jul–Sep 202584 flights85.7%
Oct–Dec 202525 flights—
Jan–Mar 202686 flights77.1%
Apr–Jun 202670 flights77.1%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 82.1% on time across 265 flights.

Quarter by quarter Republic on LEX to DTW held fairly steady: 85.7% in Jul–Sep 2025, 77.1% in Jan–Mar 2026 and 77.1% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Saturday is the strongest day at 88.1% on time and Sunday the weakest at 70.6%. 18 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. Carrier accounts for 60% of the 4,148 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
27%
National Airspace System
9%
Extreme weather
4%

The largest share of delay minutes, 60%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,488 of the 4,148 delay minutes reported here. The split is drawn from 4,148 reported delay minutes.

Cancellations are rare at 0.75%, below the national 1.81% 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 stage length

What a delay here costs

8.4% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, 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 5pm–8pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 87.0% on time across 265 flights, 5 points above 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 5 points of difference.

One caution: this is a thin sample. 265 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 LEX to DTW

Put together: treat all of this as provisional. 265 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 82.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 262 completed flights over 12 months sit behind that.
