There’s nothing quite like scoring a seat in an otherwise empty row or discovering there’s a vacant middle seat between you and your seatmate. Extra space is never cherished more than on long-haul flights where you’re spending hours in a seat that feels too stiff and too small. But as any seasoned traveler knows, the rarity of extra space is even more unlikely on certain flight routes where airlines add extra flights just to keep up with demand.

The flight between New York City (JFK) and San Francisco (SFO) was ranked the busiest long-haul flight in the world according to OAG, who analyzed the number of flights between March 2018 and February 2019. During that time period, there were 15,587 flights between the two cities operating on four airline carriers.

According to the report, eight of the 10 busiest long-haul routes in the world operate within the U.S. Following the JFK to SFO route is JFK to London Heathrow (LHR) with 14,195 flights and Honolulu (HNL) to Los Angeles International (LAX) with 11,628 flights during that time period. A long-haul route is defined by OAG as being over 3,500 km (2,175 miles).

Here are the 10 busiest long-haul flight routes in the world:

  1. JFK-SFO, 15,587 flights
  2. JFK-LHR, 14,195 flights
  3. HNL-LAX, 11,628 flights
  4. EWR-SFO, 11,302 flights
  5. BOS-LAX, 11,262 flights
  6. BOS-SFO, 10,475 flights
  7. HNL-NRT, 7,644 flights
  8. DXB-LHR, 7,109 flights
  9. LAX-LHR, 6,677 flights
  10. SIN-SYD, 6,048 flights
