British Airways BA112 flies the jet-stream exposed corridor from New York to London. Conditions change hour to hour — view the live forecast for your departure date.
View live forecastJet-stream exposure on this corridor is significant. Long mid-latitude legs mean clear-air turbulence is the dominant source of bumps, typically encountered at cruise altitude. Flying eastbound, aircraft usually benefit from tailwinds near the jet core, which trims flight time — but the edges of the jet are where clear-air turbulence most often sits.
Calmest season: May–September. The North Atlantic track sees its strongest jet-stream activity from November through February, when winds commonly exceed 150 kt and clear-air turbulence is more frequent.
