The effects of climate change could extend transatlantic flights, according to researchers from the University of Reading.
A study, published Wednesday in the journal Environmental Research Letters and led by atmospheric scientist Paul Williams, has found that an acceleration of the jet stream will mean faster flights from the U.S. to Europe, but longer flights in the opposite direction.
Jet streams are very strong winds that move weather systems around the world and can reach speeds of 200 miles an hour.
Researchers looked at the effects of doubling CO2 in the atmosphere, and calculated that jet-stream winds between New York and London would become around 15 percent faster during the winter, with similar results during other times of the year.
As such, flights towards London would become "approximately twice as likely" to be under five hours and 20 minutes, with an increased chance that flights to New York would exceed seven hours.
