Which are the consequences of having two different passports with the same name?

Having two different passports with the same name can have the following consequences ¹:

Same name, dual citizenship okay: If you have the same name in both passports and both countries accept dual citizenship, you can show the passport of the country you're going to at check-in and the passport for the country you're in at exit immigration. - Different names, dual citizenship okay: If your names are different but both countries accept each other, book your flight with the name on your A passport, show your A passport at check-in, and show your B passport at arrival immigration. - Same name, dual citizenship not okay: If one or both countries don't accept dual citizenship, book a flight from A to B via a neutral third country C, show your A passport at check-in, and show your B passport at arrival immigration in country B. - Different names, dual citizenship not okay: If you have different names and countries that don't accept each other, book your A-C-A flight in your "A" name and your C-B-C flight in your "B" name. Please note that having multiple passports can be useful for traveling to countries that have restrictions based on nationality or visa requirements. However, it's essential to handle your passports correctly and be aware of the regulations and potential issues that may arise. https://travel.stackexchange.com/questions/52100/i-have-two-passports-nationalities-how-do-i-use-them-when-i-travel
