divorced father flying with daughter - authorization letter needed?

Hey there!

I am portuguese, and so is my family, but studying in Budapest this year. My parents are divorced, and so my father is going to fly with my sister to visit me in a week. However, he won't be flying from Portugal, they will fly from Madrid. Does my father need to carry an authorization letter from my mother where she states she allows her minor daughter to travel with her father? will they request it at the airport?

I know that if they were flying from Portugal they would need it, because she cant leave the country without my mom's authorization, in theory. but as they are driving to Madrid, they will be already outside Portugal, so most likely they won't ask for any letter at the airport right?

Thanks in advance! Reply to this
