I just traveled with my 6 months old baby last month on SQ, even though is not BA. Ya, I agree that it is very easy to travel without infant. I had to stuff all the necessary items inside both my wife and my carry on. While still need to prepare a easily accessible bag.

But the worst part still the Y seat at bulkhead where you reserve for bassinet. It just simply too narrow, and I being the one suffer as I had to sit in the middle and being sandwich by wife+baby and a stranger...
