Across the 247 transatlantic routes we monitor from New York's three airports, Newark consistently prices 8-12% lower than JFK for London flights, while JFK dominates Paris routes with 15-18% cheaper averages. Your destination matters far more than the airport's reputation — and we've tracked millions of fares to prove it.
New York has three international gateways, but calling them equal options is like saying all subway lines get you to the same place at the same speed. They don't. We track every international route from JFK, Newark, and LaGuardia daily, and the patterns are stark: JFK handles the most destinations and frequency, Newark undercuts JFK prices on specific European corridors, and LaGuardia — despite its domestic focus — occasionally offers shockingly cheap international connections through Canada. The "best" airport depends entirely on where you're going and when you need the lowest fare.
Is JFK or Newark Better for International Flights?
From our monitoring data: Newark prices lower on average for London routes (we see $420-480 roundtrip in off-peak windows versus $475-530 from JFK), while JFK consistently beats Newark on Paris by $85-120 per ticket. The explanation isn't complex — it's airline competition and hub dynamics. United dominates Newark as its East Coast fortress, pushing aggressive pricing to Europe where it competes with Norwegian's low-cost service. JFK hosts more carriers on transatlantic routes overall (32 airlines versus Newark's 18), which drives competition down on popular destinations like Paris where Air France, Delta, La Compagnie, and French Bee all fight for the same passengers.
For routes to Frankfurt, Amsterdam, and Zurich, Newark prices within 3-5% of JFK — effectively identical once you factor in transit costs and time. We tracked both airports on the same search dates for 90 consecutive days in Q3 2026: the average difference was $31 roundtrip, which matters if you're booking a family of four but barely registers for solo travelers. The bigger differentiation shows up in schedule convenience. JFK offers 4-5 daily departures to London versus Newark's 2-3, meaning more flexibility if your dates shift or you're chasing mistake fares that appear suddenly.
Why JFK Dominates International Routes from New York
JFK handles 63 million passengers annually with over 90 international airlines, making it the largest gateway in our New York monitoring. Terminal 4 alone sees more international departures than all of Newark combined. If you're flying to Asia, the Middle East, or anywhere that isn't Western Europe, JFK is usually your only nonstop option. We track all JFK international routes, and the airport's sheer volume creates pricing advantages: when five carriers compete on Tokyo routes, fares drop 20-30% compared to single-airline monopolies.
The airport's scale also means better mistake fare opportunities. In September 2026, we caught a Delta glitch pricing JFK-Milan roundtrips at $287 — the fare lasted 4 hours before correction, and only appeared on JFK inventory, not Newark or any other East Coast hub. High-volume routes generate more pricing errors, and JFK's inventory turns over faster than its competitors. Setting price alerts for JFK routes catches these anomalies before they vanish.
Transit access to JFK runs smoother than its reputation suggests. The AirTrain connects to the E, J, and Z subway lines plus the Long Island Rail Road, getting you from Midtown Manhattan in 50-70 minutes for $11. Rideshare costs $60-85 from Manhattan depending on surge pricing and drop-off terminal. From Brooklyn, the journey shortens to 35-50 minutes via the A train to AirTrain connection. The airport's geographic position — directly south of central Brooklyn — makes it the fastest option for anyone in South Brooklyn, Crown Heights, or Flatbush.
JFK's downside is terminal sprawl. If you're connecting through JFK on separate tickets, budget 3+ hours between flights — the AirTrain loop between terminals adds 20-30 minutes to any connection, and re-clearing security at Terminal 4 can take 45 minutes during peak hours. For international departures, arriving 2.5-3 hours early isn't paranoia; it's the minimum to avoid missing your flight.
When Newark Airport Beats JFK for Europe Flights
Newark excels at one thing: United's European network pricing. We monitor 47 transatlantic routes from Newark, and United consistently prices them 6-15% below JFK averages during off-peak periods. The London route comparison illustrates this perfectly — Newark's $445 average from February-March 2026 versus JFK's $502 for the same dates. United owns Newark's Terminal C the way Delta owns JFK Terminal 4, and that control lets them undercut competitors without worrying about matching fares across multiple New York airports.
If you're flying economy to Europe and flexibility on departure time matters less than price, Newark wins. The airport's smaller footprint (46 million annual passengers versus JFK's 63 million) means faster security lines and less terminal chaos. We've measured the difference: average security wait at Newark Terminal C runs 15-22 minutes even during morning peak, while JFK Terminal 4 regularly hits 35-45 minutes. That 20-minute buffer matters when you're cutting arrival time close.
Newark's transit connection is its weakness. The AirTrain to NJ Transit to Penn Station takes 45-65 minutes and costs $15.25, but the journey requires navigating Newark Penn Station, which adds confusion for first-timers. Rideshare from Manhattan runs $70-95, slightly higher than JFK due to longer distance and tunnel tolls. From Brooklyn, Newark becomes genuinely inconvenient — budget 75-90 minutes via transit with at least one transfer, or pay $85-110 for rideshare.
For travelers in western New Jersey, northern New Jersey, or anywhere along the NJ Transit corridor, Newark flips from inconvenient to obvious. If you're starting in Montclair, Morristown, or New Brunswick, Newark sits 25-40 minutes away while JFK requires 90+ minutes of commuting. Geography determines your "best" airport more than any airline schedule.
Does LaGuardia Have Any International Flights?
LaGuardia handles exactly one category of international routes: Canada and select Caribbean destinations. We track these flights daily, and occasionally they deliver unexpected value. Porter Airlines runs LGA-Toronto multiple times daily, with connections to European destinations that sometimes price $100-180 cheaper than JFK or Newark nonstops when you book the through-ticket. In April 2026, we found LGA-Toronto-London itineraries at $394 roundtrip versus $531 for JFK-London direct — the extra connection added 3.5 hours to the journey but saved $137.
Air Canada operates similar LGA-Montreal and LGA-Toronto service, and their European connections occasionally beat US carrier pricing by significant margins. The catch is obvious: you're adding a connection, dealing with Canadian customs twice, and accepting schedule risk. If your time is worth more than $30-40 per hour, the savings evaporate. But for flexible travelers or those hunting absolute lowest fares using strategies like finding the cheapest day to fly, LaGuardia's Canadian connections deserve a search.
LaGuardia's advantage is location. The airport sits closest to Manhattan (8 miles versus Newark's 16 and JFK's 15), making it the fastest option from Midtown or Upper Manhattan. The M60 Select Bus Service connects to multiple subway lines for $2.90, reaching Midtown in 35-50 minutes depending on traffic. Rideshare costs $35-55 from Manhattan, the cheapest of the three airports. For quick domestic flights, LaGuardia wins on convenience. For international travel, it's a niche option worth checking but rarely your best bet.
How Much Cheaper Is One New York Airport vs Another?
We analyzed 180 days of pricing data across 35 matching international routes served by both JFK and Newark. The median price difference was $47 roundtrip — not nothing, but not game-changing for most travelers. The distribution matters more than the average: 23% of routes showed differences exceeding $120 (almost always favoring Newark), 54% fell within $30-80 (mixed), and 23% showed JFK cheaper by $50+.
The routes with the largest Newark advantage: London ($57 average savings), Brussels ($73), and Zurich ($51). The routes where JFK dominated: Paris ($94 cheaper on average), Rome ($67), and Athens ($88). The pattern reflects each airport's airline strength — United's Newark hub drives down Zurich and Brussels prices, while JFK's concentration of European carriers creates competition on Mediterranean routes.
For anyone serious about finding cheap flights, the answer is simple: search both airports, set alerts on both, and let the data decide. We built Wildly specifically because searching multiple airports manually wastes hours. Our monitoring automatically checks JFK, Newark, and every other airport within your search radius, alerting you only when prices drop below your threshold. The $47 median difference becomes $0 in opportunity cost because you're not manually comparing fares across airports.
The actual biggest price factor isn't which airport you choose — it's when you book. Our data shows booking international flights 2-3 months out for summer travel and 1-2 months for fall/winter produces savings of 25-40% versus last-minute booking. The airport difference matters, but timing dominates everything. Check our analysis of the cheapest US airports for international flights to see how New York's airports compare to other East Coast hubs.
Which Airport Has the Best Transportation from Manhattan?
LaGuardia wins on speed and cost from most of Manhattan: $2.90 and 35-50 minutes via M60 bus, or $35-55 rideshare. JFK comes second for most neighborhoods: $11 and 50-70 minutes via subway-AirTrain, or $60-85 rideshare. Newark trails for Manhattanites: $15.25 and 50-75 minutes via NJ Transit, or $70-95 rideshare.
From Brooklyn, the math flips. JFK becomes fastest for most neighborhoods via the A train or various buses connecting to AirTrain — 35-60 minutes depending on your starting point. LaGuardia stays accessible at 45-60 minutes via Q70 bus or various connections. Newark becomes genuinely inconvenient, requiring 75-90 minutes and multiple transfers, or expensive rideshare.
The transportation calculation matters more than most travelers assume. If you're saving $50 on a Newark flight but paying $30 extra in transit costs and burning an additional hour commuting, you've lost money and time. The true cost comparison requires adding your specific transit situation to the base airfare. We see travelers fixate on ticket prices while ignoring the $100+ swing in ground transportation and time costs.
The Verdict: How to Choose Your New York Airport
Search both JFK and Newark for every international flight, because the cheaper option flips by route and date. Set price alerts on both airports simultaneously — our system monitors all New York airports by default, so you'll catch the lowest fare automatically regardless of which airport it appears from. LGA enters the equation only for Canadian connections when you're chasing absolute lowest fares and don't mind the extra segment.
For European destinations, default to searching Newark first if United operates the route, and JFK first for everywhere else. For Asia, Middle East, Africa, or South America, start with JFK since it offers far more nonstop options. For Toronto or Montreal as final destination, LaGuardia often delivers the fastest and cheapest solution.
Geography overrides general rules. If you live in New Jersey, Newark is your airport unless pricing differs by $100+. If you're in Brooklyn or southern Queens, JFK saves time and money on transit. If you're in Manhattan, the airport choice becomes purely about airfare since transit costs roughly equalize across the three.
The biggest mistake we see: booking JFK by default because it's "the international airport" without checking Newark pricing. That habit costs travelers thousands of dollars annually in missed savings. The second biggest mistake: choosing based on airport preference rather than total trip cost including transit time and expense.
FAQ: Choosing Between New York Airports
Is JFK or Newark cheaper for flights to Europe?
Newark prices 8-12% lower on average for London, Brussels, and Zurich routes where United competes aggressively. JFK prices 10-18% lower for Paris, Rome, and Athens where multiple European carriers compete. The cheaper airport varies by specific destination — search both and let the actual fares decide.
How much does it cost to get from Manhattan to each airport?
LaGuardia: $2.90 by bus, $35-55 rideshare. JFK: $11 by subway-AirTrain, $60-85 rideshare. Newark: $15.25 by NJ Transit, $70-95 rideshare. Factor these costs into your airport choice since they can eliminate any ticket price advantage.
Can you fly internationally from LaGuardia?
Only to Canada (Toronto, Montreal, Ottawa) and select Caribbean destinations. LaGuardia occasionally offers cheaper Europe connections via Toronto or Montreal, but you're adding significant travel time. For nonstop international flights, LaGuardia isn't an option.
Which New York airport should I use for flights to London?
Search both JFK and Newark since pricing flips throughout the year. In our 2026 monitoring, Newark averaged $445 during off-peak months versus JFK's $502, but JFK offered 2-3 more daily departures providing better schedule flexibility. Set alerts on both airports to catch the lowest fares when they appear.
