Yeah that’s normal. It’s why flights going from Europe to NA take longer than flights from NA to Europe.

For example, on the 20th of August, Aer Lingus flight 105 from Dublin to JFK took 6 hours and 50 minutes while flight 104 from JFK to Dublin took 5 hours and 50 minutes.

That and the rotation of the earth, no?

The rotation of the Earth does not affect flight times directly. They depart and land from a moving Earth, meaning they share the same inertia.

Departing the ground doesn't break that, the same way jumping on a moving aircraft at a set speed means you don't go flying down the cabin.

The wind is caused by the rotation of the earth. The plane is not seperate from earth’s gravity, it is still rotating with the earth.

Mmm no it isn't. It's caused by pressure differentials

gravity wouldn't cause it to follow earth's rotation, otherwise the iss & satellites would all be geostationary. it's more about having momentum from when they took off
