attach player to airplane

Hi,

Sorry, since Im new to this I have no idea how it works.

Im building a platform game. From the beginning he is walking, but at one point in the level there is an airplane parked. I want my player to jump into the plane and then it will move upwards to a certain Y value keep on going when pressing froward key. And when it reaches it goal, it will automatically go down to ground again and the character jumps out. IT should go both ways. Is this possible?

So when the player is attached to the plane, the gravity properties will change, but same speed etc.
