do planes travel "faster" when they fly against the earth's rotation? are the air and ground speed the same?

No, because the air is moving with the earth. Jetstreams and winds are the reason it can be faster going one way on a flight than the return trip.

The Earth's rotation does, however, come into play when it comes to rockets. That's why they're launched East (in the direction of the Earth's rotation).
