Historical statistics for September 2025 to August 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: 6.4% of scheduled flights never operate, against 1.9% 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 1,539 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,612 at 75.4% on time.
Set against the rest of the country, Republic's DTW to EWR record is 5 points better than the US average of 77.3%. That gap is worth roughly 45 fewer late arrivals for every thousand flights.

Every carrier on DTW to EWR, 3,642 flights
These figures cover 1,539 flights between September 2025 and August 2026. The median arrival is 11 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.

Carrier by carrier
Republic against every carrier on DTW to EWR
Republic flew 1,539 of the 3,642 flights on DTW to EWR, about 42% of it. Its 81.8% on time is 4 points better than the route as a whole, which runs 77.4%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from United at 91.1% to Spirit at 67.6%. 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 75.4% of the time; Spirit Airlines manages 67.6%. Sample sizes sit next to every figure, because a two-point gap across 434 flights means less than a ten-point one.

| United Airlinesthin sample | 57 | 91.1% | 112 min | 1.75% | A |

| Spirit Airlines | 434 | 67.6% | 72 min | 8.99% | C− |
Spirit Airlines cancels 9.0% 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 15 points, against 8 points between the best and worst carrier.

- 8am–11am261 flights90.8%
- 11am–2pm262 flights83.5%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 90.8% of the time, against 75.9% for the evening window. That is 15 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 384 flights scheduled in it.
Across the year
Republic on DTW to EWR through the year
December is the weak month at 72.8% on time, against 95.0% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 153 flights.
Across the week, Wednesday is the strongest day at 84.9% on time and Sunday the weakest at 75.1%, a spread of 10 points.

Share of 1,436 completed flights by arrival against schedule.
50 of 225 late departures made up the time and arrived on time, 22% of them. In the other direction, 86 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at EWR.
The worst days
Worst days for Republic on DTW to EWR
The latest arrival of the period was on 16 December 2025, 9 hours 56 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 December 2025 | 9 hours 56 minutes | Late-arriving aircraft |
| 27 August 2026 | 7 hours 19 minutes | Late-arriving aircraft |
| 6 June 2026 | 5 hours 58 minutes | National Airspace System |

Delay causes
Why Republic runs late on this route
National Airspace System accounts for 48% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%National Airspace System
- 30%Late-arriving aircraft
- 21%Carrier
- 1%Extreme weather
48% 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 9,375 minutes out of 19,000, against a national NAS share of 21%. The split is drawn from 19,475 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.8% on time here.
Cancellations run at 6.43%, against 1.89% nationally. That is about 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
7.2% 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 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 runs 84.4% on time across 1,558 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,539 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 6.43% 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. 1,436 completed flights over 12 months sit behind that.
