Anyone else?

So my boyfriend is joining the army to help better support our family. We have a 2 year old boy and another in the way... he leaves in 2 weeks to go to basics he comes back a week before Christmas and he told me that if by any chance the baby is born early.. like our first son was.. example: if my obgyn says that I’m dilated to 2cm then he says I should call Red Cross and tell them where he is stationed and that I’m due to go into labor early so they can fly him home.. I’m freaking out cause that seems like it’s gonna be my reality soon. Last ultrasound appointment we had I was told that baby boy is showing 5 days bigger. They won’t change the due date cause it’s not an official week before he’s supposed to be born so now I’m just worrying because according to what they said then baby would be due December 18th instead if 23rd. I’m just wondering if anyone else had to go thru something similar and was there a happy ending with him making it home in time?
