I am dual national of country X and Y.

When I will be traveling from country X to Y, I want to use country Y's passport.

When I will be coming back to country X from Y, I want to use country X's passport.

Would there be any issues what so ever not just on airports but in future ?

    I’ve voted to close as a duplicate of the question above, I think the answer there should tell you what you want to know. If it doesn’t, feel free to edit this question to clarify the difference (you’ll probably have to specify which countries you’re talking about) – Chris H Nov 17 '20 at 11:45
  • This used to not be a problem at all. Nowadays with systems like API where you need to enter your passport info in advance this can become a little bit more complicated depending on the airline’s systems, but this is such a common situation that there should always be a way to do it. – jcaron Nov 17 '20 at 13:31
  • Note: there are different cases, you may missed. To travel from A to B, you may use different passport when you exit A, to book a flight, and to enter in B. Also on land borders, exiting A and entering B are two different operations So, you may overthink the question. Just I recommend to book the flight with passport B (just to speed up operations: website may not know about double passports, and airport crew should double check things). – Giacomo Catenazzi Nov 18 '20 at 09:43

That's generally not a good idea. Whether it's actually a real problem depends on your specific citizenships.

Best & safest rule in my experience is

Always enter and leave a country on the same passport

Keep in mind that the round trip contains 4 border interactions, not just 2. Leave X, enter Y, leave Y, enter X.

So if you are going from X to Y you should use BOTH passports: PassX to exit X and PassY to enter Y. On the return do it the other way around use PassY to exit Y an PassX to enter X.

You can use two passports for a single flight and Airlines are perfectly capable of handling two passports when you check in.

CAVEAT: there are over 30,000 combination of X and Y and this post is only inteded to cover the "typical" rules. Many countries don't have exit controls (US) and many countries simply don't care which passport you use.

  • A common exception to the rule: in general if someone with multiple nationalities has entered one of the countries of nationality using a foreign passport, it's fine to leave showing the country's own passport. – phoog Nov 17 '20 at 15:07
  • @phoog Wouldn't that cause problems if you ever try to use the foreign passport to enter or leave again, because the system will think you overstayed? – lambshaanxy Nov 17 '20 at 15:24
