Re: Surely it wil average out
That was my first thought as well. The article fudges around the issue with this quote :
"The good news is that eastbound flights will be boosted by stronger tailwinds, but not enough to compensate for the longer westbound journeys. The net result is that round trip journeys will significantly lengthen."
I have no idea why the westbound journeys should be longer - something to do with earth's rotation?
