Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on LGA to DTW carries a cancellation problem, not just a delay problem: 5.1% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,052 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,982 at 81.0% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on LGA to DTW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Republic against every carrier on LGA to DTW
Republic flew 1,052 of the 3,861 flights on LGA to DTW, about 27% of it. Its 74.1% on time is 3 points worse than the route as a whole, which runs 77.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 81.0% to Spirit at 72.1%.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 81.0% of the time; Spirit Airlines manages 72.1%. Sample sizes sit next to every figure, because a two-point gap across 827 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 1,982 | 81.0% | 87 min | 4.09% | B− |
| Republic Airways (this page) | 1,052 | 74.1% | 74 min | 5.13% | C− |
| Spirit Airlines | 827 | 72.1% | 88 min | 8.10% | C− |
Spirit Airlines cancels 8.1% 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 21 points, against 9 points between the best and worst carrier.
- 5am–8am—
- 8am–11am335 flights83.2%
- 11am–2pm59 flights76.3%
- 2pm–5pm343 flights73.5%
- 5pm–8pm71 flights70.0%
- 8pm–5am244 flights62.5%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 62.5% on time, against 83.2% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 343 flights scheduled in it.
Across the year
Republic on LGA to DTW through the year
December is the weak month at 63.6% on time, against 86.9% 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. October was the busiest month here, with 112 flights.
Across the week, Friday is the strongest day at 82.4% on time and Thursday the weakest at 66.4%, a spread of 16 points.

Share of 998 completed flights by arrival against schedule.
35 of 220 late departures made up the time and arrived on time, 16% of them. In the other direction, 73 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 DTW.
The worst days
Worst days for Republic on LGA to DTW
The latest arrival of the period was on 3 July 2026, 14 hours 52 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 |
|---|---|---|
| 3 July 2026 | 14 hours 52 minutes | Late-arriving aircraft |
| 22 June 2026 | 12 hours 3 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 58% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 23%National Airspace System
- 12%Carrier
- 7%Extreme weather
- 0%Security
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 19,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 19,067 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 83.2% on time here.
Cancellations run at 5.13%, against 1.89% nationally. That is about one flight in twenty 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
10.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 502 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg runs 76.8% on time across 1,052 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.
One caution: this is a thin sample. 1,052 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 LGA to DTW
Put together: the delay figures matter less here than the 5.13% 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. 998 completed flights over 12 months sit behind that.
