Hi,

Not quite the same, but we flew from Melbourne to the Whitsundays (4hrs or so), when our bub was 3 weeks old - and he slept the whole way....

I just made sure I feed him on the way up and the way down for his ears...

I'm glad I did it then rather then later, we figured if we were going to be sleep deprived we may as well be sleep deprived in the Whitsundays....

Good Luck
