Concept for a "Space Taxi"-like game

Hi guys,

I am currently trying to develop a space taxi-like game and I am not sure how the game logic is being developed - from a conceptional point of view.

As a player you got a taxi that can fly and there are several platforms on which passengers show up in a certain order and you have to land on the platform, pick up the passenger and fly the passenger to the right platform, and then the passenger exits and disappears.

you can have a short demo over here at a youtube video: https://www.youtube.com/watch?v=KuRyiFg6FBY

For now I am not sure how this description would look like in a logic sense so that I can put it into lines of code.

I must say I am not a very experienced developer and I am new to coding games. Do you have any ideas, hints, helping hands and thoughts?

Thanks and cheers
