✈️ Flight Guide: New York (JFK) → London (LHR)

April brings events that can affect both sides of the JFK–LHR route. In London, the London Marathon often occurs in April, drawing crowds and potentially affecting transport times and hotel availability near central London. Easter holidays can also increase demand for flights and produce higher fares or fuller flights on the transatlantic route. On the New York side, events like the Tribeca Film Festival (often in April) can increase airport traffic and local demand around John F. Kennedy International Airport (JFK). Plan accommodations and book flights early if your April trip coincides with these events.

April is a favorable month to fly from John F. Kennedy International Airport (JFK) to London Heathrow (LHR) because it sits in the spring shoulder season: weather improves in London, tourist crowds are smaller than summer, and fares can be more attractive than peak summer rates. Mid-week departures (Tuesday–Thursday) are often cheaper and less crowded than weekend travel, while late-evening departures can offer lower fares and arrive in London the following morning. Keep in mind holiday spikes around Easter; avoid peak holiday dates if seeking the lowest price.

Nonstop flights from John F. Kennedy International Airport (JFK) to London Heathrow (LHR) offer the fastest and most convenient option, typically operated by British Airways, Virgin Atlantic, American Airlines, and Delta. Connecting flights can be cheaper and provide more schedule flexibility, common layover hubs include Dublin, Reykjavik, or European hubs like Amsterdam and Paris for one-stop itineraries; however, connections add travel time and risk of missed connections. In April, weigh cost savings against extra transit time — if you need to arrive in London early in the day, a nonstop red-eye arrival may be preferable.

For April travel on the JFK–LHR route, compare these common carriers: British Airways emphasizes premium cabin service and direct Heathrow access from Terminal 7/5 depending on route; Virgin Atlantic focuses on stylish onboard amenities and a strong Upper Class product; American Airlines and Delta offer competitive pricing and multiple daily departures often tied to alliance partners. Expect differences in baggage allowances, seat pitch in economy, and lounge access — premium economy and business class vary by carrier. When choosing, weigh price against comfort for an overnight flight, and consider frequent flyer benefits if you fly often between New York and London.

Pack layers and a light waterproof jacket for London in April, as spring weather can be changeable with cool mornings and occasional rain. To minimize jet lag between New York and London, try to sleep on the eastbound overnight flight and get sunlight on arrival; stay hydrated and avoid heavy alcohol. Confirm baggage allowances and carry essential documents (passport, boarding pass, travel insurance) accessible during transit. Finally, sign up for flight alerts and monitor weather for both JFK and LHR on your travel day to anticipate any disruptions.

Typical nonstop flight time from John F. Kennedy International Airport (JFK) to London Heathrow (LHR) in April ranges from about 6 hours 45 minutes to 7 hours 30 minutes eastbound, and 7 hours to 8 hours westbound depending on winds and routing. Time difference: London is generally 4–5 hours ahead of New York (depending on daylight saving time transitions), so plan for jet lag and schedule impacts. Airlines often schedule overnight red-eye departures from JFK arriving in London the next morning, which many travelers prefer for better alignment with business hours in London.

To score cheap JFK to LHR flights in April, search flexible dates (mid-week typically cheaper than weekends), set fare alerts, and compare both nonstop and connecting itineraries. Book 6–8 weeks ahead for the best balance of price and availability around spring events; for Easter travel, plan even earlier. Use multiple sources — Google Flights, Skyscanner, and airline sites — to cross-check prices and watch for flash sales from carriers offering transatlantic discounts. Consider traveling slightly outside peak holiday weekends, flying late-night departures, or taking a one-stop option to reduce fares.
