Check bags are fun. I just make sure there won't be anything illegal in my check bag which is forbidden at a cabin of a plane. Just leaving things like scissors and such out of my carry-on things in order to avoid troubles with some certain airline, y'know.
Families, particularly, tend to be the ones that you take the most for granted. They seem to slip under the radar, all those important things - it almost becomes second nature to do so.
