Thanks sneaky sparkle. I do have a baby bjorn although hardly used it. DD isn't as much of a fan and her legs are so long they are constantly in my way so prefer to use the sling on the hip.

I will request with Qantas to have a bassinet seat (if the plane we travel on has them) as she is only pettite and light so should still fit in one. I'm thinking the flight will be quite busy though given that it is the end of school holidays and a Friday night.
