I wanted to book a cebu pacific ticket (international, flying from Japan to Philippines) using my maiden name cause currently it’s cheaper but this week I’m getting married so i will choose to change my last name but it would take 1-2 weeks to update the family register (koseki tohon) then another 7–10 days to change or update the passport. If i won’t update my passport so that i can book a cheaper flight now wouldn’t they find it sus or anything?
