Which New York Airport Has the Best On-Time Record: JFK, LaGuardia, or Newark?

JFK has the best overall on-time record of New York's three major airports, arriving on time 77.8% of the time with the lowest cancellation rate (2.4%). LaGuardia cancels the most flights (3.4%) and posts the weakest arrival on-time rate (75.6%), while Newark lands in between despite its delay-prone reputation.

Here's what the data shows:

• JFK posts the best arrival on-time rate (77.8%) and the lowest cancellation rate (2.4%) of the three.
• LaGuardia cancels the most flights (3.4%) and has the weakest arrival on-time rate (75.6%), despite a departure rate (78.9%) close to JFK's.
• Newark's on-time rates (78.5% departures, 75.2% arrivals) are nearly identical to LaGuardia's — its reputation for delays outruns its actual mid-pack performance.
• All three airports hit their worst on-time performance around 10 p.m., after a full day of delays has compounded.
• Based on FlightRecord's dataset of 14.1M US DOT flight records, June 2024–May 2026.

Which New York airport has the best on-time record overall?

JFK. Across 753,893 combined departures recorded at JFK, LaGuardia, and Newark between June 2024 and May 2026, JFK comes out on top on the metric that matters most once you're already at the gate: arriving close to schedule. Here's the full breakdown for each airport:

• JFK — 219,124 departures, 79.4% on-time departures, 77.8% on-time arrivals, 2.4% cancelled.
• LaGuardia (LGA) — 287,723 departures, 78.9% on-time departures, 75.6% on-time arrivals, 3.4% cancelled.
• Newark (EWR) — 247,046 departures, 78.5% on-time departures, 75.2% on-time arrivals, 2.8% cancelled.

LaGuardia handles the most departures of the three, but volume and reliability don't move together here — it's also the least reliable on arrivals and cancellations. For the full reliability picture across every US airport, see FlightRecord's most reliable airports ranking.

How do JFK, LaGuardia, and Newark compare on departures vs. arrivals?

Departure on-time rates across the three airports are close — 79.4% at JFK, 78.9% at LaGuardia, 78.5% at Newark — but arrival rates spread out more, which means delays compound differently after wheels-up at each airport. Average delay minutes tell the same story:

• JFK — 16.9 min average departure delay, 18.8 min average arrival delay (a 1.9-minute gap).
• LaGuardia — 17.4 min average departure delay, 19.5 min average arrival delay (a 2.1-minute gap).
• Newark — 18.2 min average departure delay, 21.8 min average arrival delay (a 3.6-minute gap, the widest of the three).

Newark's gate operations aren't dramatically worse than LaGuardia's, but its flights lose more time in the air or on approach than either of the other two — consistent with Newark's position under some of the most congested airspace on the East Coast.

Why does Newark get blamed for delays when it's not the worst?

Newark's reputation for delays is well earned in the news cycle, but the FlightRecord data puts it squarely in the middle of the pack, not at the bottom. Its cancellation rate (2.8%) is meaningfully better than LaGuardia's (3.4%), and its arrival on-time rate (75.2%) is essentially tied with LaGuardia's (75.6%). Where Newark actually trails is departures — its 78.5% on-time departure rate is the lowest of the three, just behind LaGuardia's 78.9%. The airport most likely to leave you sitting at the gate isn't necessarily the one with the worst headlines.

What time of day should you avoid flying through each NYC airport?

Hour-by-hour on-time rates reveal a consistent pattern: mornings are reliable everywhere, and the last flights of the night are not.

• JFK — best hour is 7 a.m. (90.8% on-time, 18,186 flights); worst is 10 p.m. (66.8% on-time, 5,211 flights, 24.8-minute average departure delay). Even JFK's busiest hour, 8 a.m., holds up well at 87.7% on-time across 19,357 flights.
• LaGuardia — best hour is 6 a.m. (93.2% on-time, 21,090 flights); worst is 10 p.m. (57.2% on-time, 1,595 flights, a 46.8-minute average departure delay — the worst single hour of any NYC airport). LaGuardia's busiest hour, 3 p.m., is also one of its weaker ones at 72.4% on-time across 21,418 flights.
• Newark — best and busiest hour are the same: 6 a.m., with 91.2% on-time performance across 20,715 flights. Its worst hour is 10 p.m. (58.2% on-time, 2,836 flights, 38.7-minute average delay).

The takeaway holds across all three airports: an early-morning departure, ideally before 7 a.m., is your most reliable option. A LaGuardia flight scheduled for 10 p.m. runs nearly 47 minutes late on average — the single worst hour-airport combination in the New York market.

Which airlines are most reliable at each NYC airport?

On-time performance also depends heavily on which airline you fly, not just which airport you depart from:

• JFK — American (AA) leads at 83.9% on-time across 28,806 flights, with Republic Airways' regional flights (YX) close behind at 83.3% (32,892 flights) and Delta (DL) at 81.0% (61,026 flights). JetBlue (B6), JFK's largest operator by volume with 71,105 flights, lags the group at 73.8%.
• LaGuardia — Republic Airways (YX) is both LaGuardia's biggest operator (103,223 flights) and its most reliable major carrier at 81.7% on-time. Delta (DL) follows at 78.3% (57,641 flights) and American (AA) at 77.1% (33,215 flights); Southwest (WN) is weakest of the group at 71.2% (23,369 flights).
• Newark — Republic Airways (YX) again leads at 85.7% on-time (45,035 flights). United (UA), Newark's dominant carrier with 134,734 flights — more than half of all Newark departures — posts a middling 77.7%, and Spirit (NK) trails at 72.8% (18,456 flights).

Should you switch NYC airports for a more reliable flight?

If your trip allows flexibility, the data supports a real trade-off: JFK for the best combined reliability, Newark if JFK isn't practical and you can book an early flight, and LaGuardia last if avoiding cancellations and late-night delays matters most. New York is one of the few US metros where three major airports genuinely compete for the same routes, so it's worth checking whether a nearby-airport swap gets you a materially better on-time record — FlightRecord's guide on flying from a different nearby airport walks through how to evaluate that trade-off in general.

If you're comparing other multi-airport metro areas, FlightRecord has run the same analysis for Washington DC's Dulles, Reagan National, and BWI, and for Chicago's O'Hare and Midway.

Methodology: we compared departure on-time rates, arrival on-time rates, cancellation rates, hourly on-time patterns, and per-carrier on-time rates across the three airports serving New York City, using FlightRecord's dataset of US DOT on-time performance records from June 2024 through May 2026. On-time is the DOT standard: arrived within 15 minutes of schedule.

These are historical patterns, not a guarantee for any specific upcoming flight — weather, air traffic control, and aircraft rotations can all push an individual departure well outside its airport's typical range. Check the current status of your own flight number before you travel.

Frequently Asked Questions

Is JFK really more reliable than LaGuardia and Newark?

Yes, on arrivals. Based on FlightRecord's June 2024–May 2026 dataset, JFK's 77.8% arrival on-time rate beats LaGuardia's 75.6% and Newark's 75.2%, and JFK also cancels the fewest flights (2.4%). Departure on-time rates are closer — 79.4% at JFK versus 78.9% at LaGuardia and 78.5% at Newark — but the gap widens once flights are airborne.

Why does LaGuardia have the highest cancellation rate?

FlightRecord's data doesn't isolate a single cause, but the gap is real: LaGuardia cancelled 3.4% of scheduled departures in the dataset, versus 2.8% at Newark and 2.4% at JFK. That's the widest pairwise cancellation gap among any two of the three airports.

Should I choose Newark over LaGuardia for a more reliable flight?

The two are close. Newark's cancellation rate (2.8%) is lower than LaGuardia's (3.4%) and its arrival on-time rate (75.2%) is nearly identical to LaGuardia's (75.6%), though LaGuardia posts a slightly higher departure on-time rate (78.9% vs. 78.5%). Neither comes close to JFK's overall reliability.

What time of day has the most reliable flights at NYC airports?

Early morning. Every NYC-area airport in FlightRecord's dataset posts its highest on-time rate before 7 a.m. — 90.8% at JFK's 7 a.m. hour, 93.2% at LaGuardia's 6 a.m. hour, and 91.2% at Newark's 6 a.m. hour. On-time performance erodes through the day and bottoms out around 10 p.m. at all three.

Which airline is most reliable at JFK, LaGuardia, and Newark?

Among higher-volume carriers, American (83.9% on-time) leads at JFK, Republic Airways' regional flights (81.7%) lead at LaGuardia, and Republic Airways (85.7%) also leads at Newark. JetBlue at JFK, Southwest at LaGuardia, and Spirit at Newark post the weakest on-time rates among each airport's busier carriers.

How much data does this comparison use?

This analysis draws on FlightRecord's dataset of 14.1 million US DOT Bureau of Transportation Statistics flight records covering June 2024 through May 2026 — including 219,124 JFK departures, 287,723 LaGuardia departures, and 247,046 Newark departures, each with matched arrival and cancellation outcomes.
