International flight

HI Shar, thank you for your enquiry, we would ot recommend using this carrier onboard any flight as you will still have to use an additional belt for the infant & it will also be very uncomfortable. We do suggest contacting your nearest store so they can advise you on the best course for you and your baby. We hope this helps. ?https://www.babyonthemove.co.nz/store-locations/
