The real problem is if there is a baby in there, and it is not yours.
On a recent 13 hour Qantas flight, my partner was stuck in coach, in the bulkhead row. Mom, dad, and baby arrive. The bassinet, though, is in front of my partner.
Needless to say, he did not have a very good flight.
Stay away from the bassinet seat, unless it is for your own child!
