DH needs to travel to Spain in May and August this year. His passport expires in June 2024 but was renewed in Nov 2013, so will be 10 years old in Nov 2023. I understand when you travel, your passport needs to be less than 10 years old and have 6 months left. Do these 6 months need to be within the 10 years? So DH can't use his passport after May (and we need to renew soon). Or is it still OK because it meets both of the criteria but separately? Hope that makes sense!
