A recently published study has found that flight times will get significantly longer on westbound transatlantic flights and shorter on eastbound journeys due to climate change.

A recently published study has found that flight times will get significantly longer on westbound transatlantic flights and shorter on eastbound journeys due to climate change.
However, the primary researcher, Paul D. Williams from the University of Reading in the UK, notes, “For reasons that are explained using a conceptual model, the eastbound shortening and westbound lengthening do not cancel out, causing round-trip journey times to increase.” 
As a result, even without any growth in air travel, his data suggests that aircraft will be flying for
