Delta on LGA to RSW sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 669 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Delta on LGA to RSW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Delta against every carrier on LGA to RSW
Delta flew 669 of the 869 flights on LGA to RSW, most of the route. Its 74.4% on time is about level with the route as a whole at 73.3%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Delta at 74.4% to American at 69.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Delta runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 22 points, against half a point between the best and worst carrier.
- 5am–8am244 flights85.1%
- 8am–11am121 flights81.2%
- 11am–2pm10 flights—

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 85.1% of the time, against 62.9% for the afternoon window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 294 flights scheduled in it.
Across the year
Delta on LGA to RSW through the year

Share of 633 completed flights by arrival against schedule.
18 of 134 late departures made up the time and arrived on time, 13% of them. In the other direction, 46 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 RSW.
The worst days
Worst days for Delta on LGA to RSW
The latest arrival of the period was on 30 January 2026, 6 hours 26 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 |
|---|---|---|
| 30 January 2026 | 6 hours 26 minutes | Carrier |
| 20 October 2025 | 6 hours 11 minutes | Carrier |
| 21 July 2026 | 5 hours 47 minutes | Carrier |
| 12 June 2026 | 5 hours 23 minutes | National Airspace System |
| 5 August 2026 | 4 hours 45 minutes | Late-arriving aircraft |
Delay causes
Why Delta runs late on this route
Carrier accounts for 42% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Carrier
- 29%National Airspace System
- 26%Late-arriving aircraft
- 3%Extreme weather
The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,561 of the 13,000 delay minutes reported here. The split is drawn from 13,207 reported delay minutes.
Cancellations run at 4.78%, 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
11.1% 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 1,080 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 is a different operation and performs like one: it runs 70.6% on time across 669 flights, 4 points below 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.
One caution: this is a thin sample. 669 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 Delta on LGA to RSW
Put together: the delay figures matter less here than the 4.78% 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. 633 completed flights over 12 months sit behind that.
