Is the flight time affected by the earth’s rotation if we go East- vs. Westward?

Question

Let’s assume we are flying at the same speed of let’s say 600 mp/h eastward and with 600 mp/h back westward: Will there be a difference in flight time?

Please ignore other factors like jetstream/windspeeds etc. for the main part and and only focus on the rotation

Now i don’t know how the speed of an Aircraft is measured/calculated but if the speeds are the same the destination should be coming closer to us and therefore we’d be faster to reach our destination, right?

Or do i have to imagine it in a sense that we are not “detached” from the earth’s movement, even while we are mid-air and are always moving at a constant speed with it and therefore it won’t matter?

Will it be easier to accelerate in one or the other direction? Will going 600 mp/h east take the same power as 600 mp/h going west?

I am so confused and i can’t even pinpoint as to why.

Thanks in advance

The atmosphere spins along with the Earth, so you aren’t going to gain/lose speed just by going with or against the Earth’s spin. If this wasn’t the case we’d constantly be experiencing 1000mph winds.
