I'm traveling to Kenya and want to use my Ethiopian passport to leave Ethiopia and enter Kenya (since it's visa-free for 90 days), then travel to the US from Kenya using my American passport. The issue is that the last names are different due to naming conventions in Ethiopia. On my Ethiopian passport, my last name is my grandfather's name and my middle name is my father's name. On my American passport, my last name is my dad's name and there is no middle name. Everything else, including the photo and date of birth, is the same. I'm worried this might cause issues with airlines or immigration, so what should I do?

I was thinking one way tickets to each country, i enter using ethiopian passport and when i exit i show airline my us passport with the ticket spelled similar to us passport, then show kenyan immigration my ethiopian passport so they can stamp the exit.…
