LaGuardia’s reputation as a delay trap is only half true. Airport-wide on-time departure rates in 2025 put LaGuardia, JFK, and Newark within about 1.5 points of each other. The real split is time of day.
Early-morning LaGuardia departures (5–8 a.m.) run roughly 88–92% on-time, close to the best in the region. By mid-afternoon and evening, LaGuardia drops to about 60–65%, while JFK holds above 67–73%. For most routes, the airport choice should follow your scheduled departure window, not a blanket preference for JFK or Newark.
For all the heat LaGuardia takes, the headline 2025 numbers don’t look like a disaster. Through June, LaGuardia posted a 77.34% on-time departure rate, Newark logged 77.98%, and JFK sat at 78.81%. That’s a near dead heat across the three airports.
But an airport-wide percentage hides the decision most travelers actually face. You’re not choosing between averages. You’re choosing a specific flight at a specific hour to a specific city. And once you split LaGuardia’s performance by departure window, the picture flips. Morning flights are genuinely reliable; afternoon and evening flights are where the pain concentrates.
This article is built around that split. It gives you a way to weigh LaGuardia’s closer Manhattan location against the higher delay risk that kicks in after midday, and explains why the airport’s operational design makes recovery from even small disruptions so slow.
LaGuardia airport delays vs. JFK and Newark: what the data shows
A true route-by-route comparison across all three airports isn’t published in the current public BTS summaries, so the practical picture comes from airport-wide rankings and time-window patterns. Year-to-date June 2025 federal data shows the three airports are statistically close on an all-departures basis. The spread from best to worst is under two percentage points. That’s not a meaningful margin for most booking decisions.
The useful data emerges when you look at departure time. Early morning at LaGuardia is not just acceptable—it’s often the region’s lowest average delay. In a BTS-based NYC analysis covering the 0:00–11:59 departure window, LaGuardia averaged 1.96 minutes of departure delay compared with 4.61 at JFK and 4.62 at Newark. By the 5–8 a.m. window, LaGuardia runs about 88–92% on-time.
By 2–5 p.m. that advantage disappears. LaGuardia falls to roughly 65% on-time departures; by 5–8 p.m. it’s about 60%. JFK holds at roughly 68–73% in those same windows. Newark’s route- and time-specific figures are not published in the same BTS-derived summaries, so the honest benchmark remains its airport-wide 77.98%—slightly ahead of LaGuardia but not by enough to make it an automatic winner.

Why LaGuardia has no recovery buffer
LaGuardia operates under a federal slot-control regime that caps total hourly takeoffs and landings. That cap is not a technical detail; it means the airport runs close to its ceiling even on good days. With only two intersecting runways, both 7,002 feet long, there is no redundant parallel runway to absorb a slowdown. When one runway closes, the field doesn’t degrade gradually—it loses half its landing capacity in an instant.
The Federal Aviation Administration has kept operating limitations in place through October 28, 2028 specifically to stop severe congestion from cascading across the national system. Long-haul traffic gets pushed to JFK and Newark by the Perimeter Rule, which caps non-stop LaGuardia flights at destinations within 1,500 miles except where exemptions apply. That concentrates shorter, high-frequency domestic flights at LaGuardia, exactly the segment most sensitive to slot and runway constraints.
When one of LaGuardia’s two runways closed on March 23, 2026, the damage spilled into JFK and Newark rebookings. Missed connections and overnight stays followed while the constrained field cleared its backlog.

The slot and staffing math underneath your delay risk
The FAA’s slot flexibility for the Winter 2026–2027 and Summer 2027 seasons lets airlines hand back up to 10% of their LaGuardia and JFK slots without losing them to use-it-or-lose-it rules. That may sound like relief, but the Federal Register notice doesn’t report which carriers actually used the option. The policy exists because the system is under pressure, not because the pressure has eased.
The controller staffing shortage at the New York Terminal Radar Approach Control remains a separate constraint. Regulatory filings say impacts will take 12–18 months to mitigate even with the current flight limits in place. For a traveler, that means the near-term booking environment still carries the same fragility: no surge capacity, no room to recover quickly.
What switching airports actually costs you on the ground
The airport decision folds in more than air delays. Ground transfer times and prices differ sharply. From LaGuardia, the cheap path is the Q70 or M60 bus plus subway, about $2.90 and 30–45 minutes to Midtown. A taxi runs $65–85 and can take 20–60 minutes depending on traffic.
JFK’s AirTrain plus LIRR costs roughly $13–17 and reaches Penn Station in about 40 minutes, with taxis at a flat about $70. Newark’s AirTrain plus NJ Transit gets to Penn Station fastest—about 25 minutes—but the fare runs around $26.75, and a taxi to Midtown typically totals $90–95 with tolls.
These differences matter more for afternoon and evening arrivals, when a LaGuardia delay can eat the ground-commute advantage. If your flight is scheduled to arrive at 6 p.m. and then sits on the tarmac for 40 minutes, the closer location has already lost much of its benefit.
What this means for your flight
If your schedule allows a departure before 8 a.m., LaGuardia is a reasonable choice. The early-morning window is far more reliable than its late-afternoon performance, and the ground transfer is cheaper and shorter than JFK or Newark.
If your preferred slot falls after 3 p.m., treat LaGuardia’s location discount with suspicion. On-time performance drops steeply in the late afternoon and early evening. In those hours, shifting to JFK or Newark often buys a more predictable gate-to-city arrival, even with the extra rail time. Newark’s rail link is fastest; LaGuardia’s bus-subway path is cheapest.
If a disruption hits while you’re already booked at LaGuardia—especially a runway closure—ask for rebooking to JFK or Newark immediately and confirm the ground transfer before accepting the new flight. The first hour after an event is when seats on those alternatives disappear.
Key terms
- Slot control
- A regulatory cap on the number of takeoffs and landings an airport can handle per hour. At LaGuardia, the FAA sets these limits to prevent congestion from overwhelming the field’s two runways. The cap is why a single runway closure at LaGuardia can cascade into hundreds of cancellations and delays across the region.
- Perimeter Rule
- A federal restriction limiting non-stop flights from LaGuardia to destinations within a set distance, currently 1,500 miles, with limited exemptions. It was designed to push long-haul traffic to JFK and Newark. The rule concentrates shorter, high-frequency domestic flights at LaGuardia, the segment most exposed to slot and runway constraints.
- Use-it-or-lose-it
- A rule requiring airlines to operate a minimum percentage of their allocated slots or forfeit them. The FAA’s waiver for Winter 2026–2027 and Summer 2027 lets carriers return up to 10% of LaGuardia and JFK slots without penalty. The waiver signals the system is under pressure, not that the pressure has eased.
- New York TRACON
- The New York Terminal Radar Approach Control, the FAA facility that manages air traffic in the busy airspace around the city’s airports. Controller staffing shortages there have forced flight limits and delays. Regulatory filings say impacts will take 12–18 months to mitigate even with current limits in place.
Questions? Answers.
Does LGA have more delays than JFK?
Not in a decisive way. LGA’s 77.34% on-time rate for year-to-date June 2025 trails JFK’s 78.81% by only about 1.5 points. The gap narrows or reverses by departure window, with LGA’s early-morning performance often better than JFK’s.
Is it better to fly into LaGuardia or JFK or Newark?
It depends on schedule and destination. LaGuardia is closest to Manhattan and its early-morning flights run roughly 88–92% on-time, but afternoon and evening reliability drops sharply. JFK and Newark offer more predictable afternoon service, with JFK around 72–73% on-time in the 2–5 p.m. window and Newark’s airport-wide rate at 77.98%. Ground transfer time also differs: LaGuardia is cheapest by bus-subway, while Newark’s rail link reaches Midtown fastest.
Does LaGuardia airport have a lot of delays?
It has a lot of afternoon and evening delays. Airport-wide, 77.34% of LaGuardia departures were on-time through June 2025, just below JFK and Newark. But time-window data shows a steep drop: from about 88–92% on-time in the 5–8 a.m. window to about 65% at 2–5 p.m. and about 60% at 5–8 p.m. A March 2026 runway closure also caused 221 cancellations and 214 delays in one day.
Is LaGuardia still delayed?
Yes, especially later in the day. LaGuardia’s 5–8 a.m. departures still run about 88–92% on-time, but by the 2–5 p.m. window the rate falls to about 65%, and by 5–8 p.m. it is about 60%. A single runway closure in March 2026 showed how quickly the airport can rack up hundreds of cancellations and delays.
Are there any delays at Newark International airport?
Yes, Newark has delays, but its overall rate is close to JFK and LaGuardia. Year-to-date June 2025 on-time departures at Newark were 77.98%, slightly below JFK’s 78.81% and above LaGuardia’s 77.34%. In the morning departure window, a BTS-based NYC analysis found Newark averaged 4.62 minutes of departure delay, higher than LaGuardia’s 1.96 minutes but similar to JFK’s 4.61 minutes.
