The London-New York pairing is one of the most lucrative segments in aviation, seeing a high amount of traffic and plenty of demand for premium cabins. In 2019, over 3.1 million passengers flew between London and New York, a route that was seeing annual growth ahead of the pandemic. Following the pandemic downturn, demand has shot back up, with London Heathrow (LHR) alone processing more than 3 million passengers to New York throughout 2023.
