Mallys right under 12weeks no vaccinations just a passport and chip don't even need any jabs don't let the vet fill u full of shit tell them u want a passport and chip that's it,, klm fly pups in cargo or in a small carrier case under your seat of 20cm the pup gotta be able to stand up and turn around but can be refused on the day if any passengers are allergic or objects I found cargo was a lot easier and no knock back on the day coz its not in the cabin they say u need to book 48hours before the flight but be safe and give yourslef a week coz they took some time confirming the pup on the
