Thanks to strong jet streams over the northern United States, a flight between Los Angeles and New York recently took less than four hours.
On Feb. 17, United flight 415 departed Los Angeles International Airport and arrived at Newark Liberty International Airport in just 226 minutes. The flight took off at 11:28 p.m. Pacific time and landed at 6:14 a.m. Eastern time.
Such unusually fast transcontinental trips are typically the result of strong west-to-east jet streams. These high-altitude winds, most common in winter, can give aircraft a significant tailwind that reduces travel time. A relative absence of major storms this season may also have helped strengthen and stabilize the jet stream, contributing to quicker crossings.
Shorter flight times bring measurable benefits for airlines. With less time in the air, aircraft consume less jet fuel and crews bill fewer hours, which lowers operational costs.
The record for the quickest Los Angeles–New York crossing was set in October 1996, when a flight completed the route in just 201 minutes.
