eli5 If I fly to the other side of the world pointing East vs the same trip heading West how much difference does the earth’s rotation make to the trip?

Thinking of a trip from the UK to Australia. Is it faster going East? Can you explain the maths of this? Thanks in advance (for my 10 year old son).

None. You were and are rotating with the Earth.

The two differences are winds (which depend a ton on latitude) and centripetal force which would make gravity appear slightly stronger or weaker (and so slightly more or less drag to stay aloft).
