Me and partner are going away tomorrow with our 6 month old son. My son has the same name as his dad however we are not married so my surname is different. Will this be an issue at the airport and will I need to show birth certificate or will this be okay seeing as my partner is with us. Birth certificate still hasn’t come back from the passport office!! Anyone with experience on this please. Friends have said this hasn’t been an issue but I guess you never know if they were just lucky! X
