This route carries a cancellation problem, not just a delay problem: 5.9% 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 1,735 LGA to GSO flights, with a median arrival 9 minutes early.
Best time to fly LGA to GSO: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 90.0% of the time and Wednesday flights 77.6%, against 74.6% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

- 8am–11am320 flights81.6%

Scale runs 60% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.0% of the time, against 68.1% 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 538 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 22 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
July is the worst month at 64.9% on time, 22 points below September, the best at 87.0%. 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. November was the busiest month here, with 210 flights.
Across the week, Wednesday is the strongest day at 77.6% on time and Sunday the weakest at 70.2%, a spread of 7 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 53% of the 28,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 24%National Airspace System
- 19%Carrier
- 4%Extreme weather
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 28,000 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 27,727 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 90.0% on time here.
Cancellations run at 5.88%, 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 actually 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.
At 461 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 5am–8am window matters as much as it does.
The return leg runs 76.0% on time across 1,737 flights, within about a point 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 1,735 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 this route
Put together: the delay figures matter less here than the 5.88% cancellation rate. A late arrival costs you about 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. 1,633 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 90.0% on time. The 2pm–5pm window is the weakest at 68.1%, 22 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
