Return flight slower?

[daysleeper]

Hey,

I am new to the game, but I was wondering the following. I scheduled a flight from Denver to London, and somehow the flight back to Denver takes one hour longer than DEN-LHR (10h30m vs 9h30m). See the screenshot attached. The distance should be the same. How is this possible?

Thanks!

It is also that the earth is moving against the direction of the plane so the distance will actually be longer.

If you hover over the ? next to the flight time, it breaks down everything: taxi time, total time aloft, and how breezy it is upstairs.

jetstream heading east over the atlantic explains it all...

If it worked like that, and plane had to catch up with the rotation of the earth, you'd be headed to Denver backwards over Asia.  The return flight is slower because of the jet stream.   Has nothing to do with the planet's rotation.
