I travelled back & fourth to Bali on numerous occasion with Maddison from 9kws of age. The minute we boarded the plane she'd fall asleep & after landing (6ish hours later) she'd wake up.. she never even noticed we'd gone anywhere & then would feed & sleep as per normal....

I honestly never moticed anything different, if anything we were on holidays & I was much more relaxed & didnt worry if she was up 30 mins later or anything... I think we did about 4 or 5 trips to bali in the first 18 months of her life...

We were staying there usually for 2 months at a time so she was getting used to it.,..

But I guess be preapared for her to be a little bit out of whack & then it wont be so much an issue... But I always would change my watch at atke off, so i was already in their time zone...
