Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on DTW to EWR carries a cancellation problem, not just a delay problem: 5.8% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,491 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,621 at 74.0% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on DTW to EWR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,491 flights between July 2025 and June 2026. Beyond the headline rate, 8.1% 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.
Carrier by carrier
Republic against every carrier on DTW to EWR
Republic flew 1,491 of the 3,764 flights on DTW to EWR, about 40% of it. Its 79.6% on time is 4 points better than the route as a whole, which runs 75.8%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from United at 91.7% to Spirit at 67.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 74.0% of the time; Spirit Airlines manages 67.7%. Sample sizes sit next to every figure, because a two-point gap across 554 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlinesthin sample | 98 | 91.7% | 97 min | 2.04% | A |
| Republic Airways (this page) | 1,491 | 79.6% | 74 min | 5.77% | B− |
| Delta Air Lines | 1,621 | 74.0% | 81 min | 3.45% | C− |
| Spirit Airlines | 554 | 67.7% | 78 min | 8.30% | C− |
Spirit Airlines cancels 8.3% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Departure window
When Republic runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am269 flights86.9%
- 8am–11am220 flights89.3%
- 11am–2pm320 flights79.7%
- 2pm–5pm265 flights78.6%
- 5pm–8pm413 flights69.6%
- 8pm–5am4 flights—
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 89.3% of the time, against 69.6% for the evening window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 413 flights scheduled in it.
Across the year
Republic on DTW to EWR through the year
July is the worst month at 58.6% on time, 36 points below May, the best at 95.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. June was the busiest month here, with 149 flights.
Across the week, Monday is the strongest day at 81.9% on time and Sunday the weakest at 74.2%. 8 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. National Airspace System accounts for 50% of the 21,000 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.
- 50%National Airspace System
- 26%Late-arriving aircraft
- 19%Carrier
- 4%Extreme weather
50% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 11,000 minutes out of 21,000, against a national NAS share of 21%. The split is drawn from 21,222 reported delay minutes.
Cancellations run at 5.77%, against 1.81% nationally. That is roughly one flight in fifteen cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
8.1% 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 a little over an hour, which a normal layover absorbs.
At 488 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 83.3% on time across 1,510 flights, 4 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 4 points of difference.
The sample behind these figures is 1,491 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking Republic on DTW to EWR
Put together: the delay figures matter less here than the 5.77% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,403 completed flights over 12 months sit behind that.
