0/1 so far - January 1 ATL to MSN on a 717 had F completely sold for weeks and last night had 5 young children and their parents. Given noise level up there I was much happier in C+.
Also, my wife (GM) was op-up'ed on a long-haul to AF business while son and I (DM) were not. Don't have to feel bad about not trading any domestic first class upgrades with her in 2018!
