Family coming from far away for birth?

How is everyone planning the dates that your family will come out for the birth of they live super far away? 
We live in Germany and my mom is in California, she can't just book a last min flight really and I want to somewhat plan it. Too expensive too haha.
I asked my doc the last day I would be induced would be 10 days after due date so thinking my mom will come out right before due date and then stay for the 2 weeks she has off and if baby comes late then she could most likely still be here.
