This route carries a cancellation problem, not just a delay problem: 5.7% 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 3,012 PIT to LGA flights, with a median arrival 9 minutes early.
Best time to fly PIT to LGA: a 5am–8am departure, ideally on a Friday. Flights in that window arrived on time 92.5% of the time and Friday flights 85.7%, against 79.9% 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.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.

Book the early departure. Flights leaving between 5am–8am arrive on time 92.5% of the time, against 66.5% for the evening window. That is 26 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 738 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 19 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.
May is the best month on the calendar at 88.7% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. September was the busiest month here, with 294 flights.
Across the week, Friday is the strongest day at 85.7% on time and Thursday the weakest at 75.5%, a spread of 10 points.
Delay causes
Why this route gets delayed
National Airspace System accounts for 52% of the 47,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%National Airspace System
- 25%Late-arriving aircraft
- 19%Carrier
- 4%Extreme weather
52% 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 24,000 minutes out of 47,000, against a national NAS share of 21%. The split is drawn from 46,789 reported delay minutes.
Cancellations run at 5.74%, 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
9.4% 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 335 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 78.3% on time across 3,013 flights, within 2 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 3,012 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 5.74% cancellation rate. A late arrival costs you an hour and a half; 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. 2,836 completed flights over 12 months sit behind that.

What time of day has the fewest delays on PIT to LGA?
The 5am–8am departure window is the strongest at 92.5% on time. The 5pm–8pm window is the weakest at 66.5%, 26 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.
How bad are March delays on PIT to LGA?
