Did you ever travel internationally along with only one of your parents? I know of many cases around the world where authorities will definitely cause you some trouble if you try to do that, even more if somehow "expected" naming conventions don't match up. At least that's how it's been in the last 2 decades.

I travel multiple times a year internationally with my toddler. She has a different last name than me. No issues whatsoever. Yes, i bring a birth cert and a letter from her mother that we can travel, but no one has ever asked for these.
