We all lived in the same state except one uncle until I left (3-4 hour plane ride away) and then went further (15 hours+ across two flights). Mom and stepfather moved south to be warmer on retiring not far from where that uncle had gone. I still live in Japan and everyone else still lives in the state I grew up.

For me, visiting family is now a more time-consuming and expensive adventure, particularly because the one airport anywhere near mom only has a couple of flights a day.

As for the in-laws in Japan, a few hours away from SiL who lives in Tokyo and about an hour away from her parents by billet train.
