How get fsx ground crew?

Commercial Jets:

Jetway: When you park at a Jetway, shut off your engines and batteries, and press Ctrl+J to get a Jetway.

Baggage Trucks: To get the baggage trucks, first thing is first: TURN YOUR ENGINES OFF. They will not come if your engines are on. Then press Shift+2 to open your baggage holds. Then they should come automatically. Also make sure that you are at a parking space that has a pushback truck. If it has that then it has the baggage trucks.

Civilian Props: All you can do is pushback (Shift+P)
