What do you do with Bub if you want to go to the loo? Need to change clothes?
Yes can ask flight attendant, or a fellow passenger to hold. I have left sleeping in bassinet and asked passenger next to keep an eye on. You can use a wrap/carrier on a plane (not allowed for take off and landing normally) and keep the baby in that and manage the toilet. When travelling solo with babies I actually found that using the toilet on the plane is much easier than trying to use it in the airport.
