I have USA & Colombia citizenship and passports. I usually use my US passport when traveling to Europe, but my US passport is expiring March 1st 2024. My Colombian passport expires in 2025, so it's fine.
I have a short trip (2 weeks) to Europe coming up in late October. I'm worried that I'm just now reading that one needs to have at least 3 months of a valid passport PAST the date one departs from EU/Schengen? I might be coming very close to that threshold in my trip.
Hypothetically, if the airline or border agent gives me trouble about the US passport expiring soon, can I just take out my other passport and use that? (Colombian citizens can also enter Schengen visa-free for tourism.)
