Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on DTW to LGA carries a cancellation problem, not just a delay problem: 5.8% 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 B− 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 1,981 at 76.4% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on DTW to LGA 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 DTW to LGA
Republic flew 1,052 of the 3,862 flights on DTW to LGA, about 27% of it. Its 76.8% on time is 2 points better than the route as a whole, which runs 74.7%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 76.8% to Spirit at 67.9%.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 76.4% of the time; Spirit Airlines manages 67.9%. Sample sizes sit next to every figure, because a two-point gap across 829 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways (this page) | 1,052 | 76.8% | 80 min | 5.80% | B− |
| Delta Air Lines | 1,981 | 76.4% | 74 min | 4.04% | B− |
| Spirit Airlines | 829 | 67.9% | 76 min | 8.32% | 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 21 points, against 9 points between the best and worst carrier.
- 5am–8am299 flights84.5%
- 8am–11am152 flights83.9%
- 11am–2pm268 flights76.8%
- 2pm–5pm26 flights—
- 5pm–8pm307 flights63.8%
- 8pm–5am—
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.8% on time, against 84.5% for the 5am–8am 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 5pm–8pm window is the busiest, with 307 flights scheduled in it.
Across the year
Republic on DTW to LGA through the year
December is the weak month at 66.7% on time, against 86.9% in April. 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, Saturday is the strongest day at 84.5% on time and Thursday the weakest at 73.2%, a spread of 11 points.
Arrival by arrival
How late Republic on DTW to LGA runs when it is late
Republic on DTW to LGA often beats the schedule: 331 of 987 completed flights, 34%, arrived 15 minutes or more early. The 229 late arrivals split 78 under half an hour, 60 between 30 and 60 minutes, and 91 an hour or more.

Share of 987 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 182 departures that left 15 minutes late or more, only 18 made it up before arrival. In the other direction, 65 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 LGA.
The worst days
Worst days for Republic on DTW to LGA
The latest arrival of the period was on 16 September 2025, 14 hours 34 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 September 2025 | 14 hours 34 minutes | Carrier |
| 27 January 2026 | 9 hours 51 minutes | Carrier |
| 14 December 2025 | 7 hours 48 minutes | Late-arriving aircraft |
| 25 February 2026 | 6 hours 32 minutes | Carrier |
| 8 January 2026 | 6 hours 19 minutes | Late-arriving aircraft |
Delay causes
Why Republic runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 18,000 reported delay minutes.
- 38%Late-arriving aircraft
- 27%National Airspace System
- 25%Carrier
- 10%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 18,000 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 18,318 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 84.5% on time here.
Cancellations run at 5.80%, against 1.89% 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
9.2% 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 74.1% 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 DTW to LGA
Put together: the delay figures matter less here than the 5.80% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 987 completed flights over 12 months sit behind that.
