Am I the only one that check all the important documents I need to prior to BOOKING international traveling then storing them in a safe place until the day of travel?
no your not, and anything else is just negligent,
documents checked to be there and in date, elastic band around them (for me 5 passports, me, missus and 3 kids) prior to booking,
checked again 5 days or so before departure,
as a father, I believe this is one of your true responsibilities to your family, can you imagine the horror, explain to 3 kids, they are not going to Disneyland after all, because Daddy's is a moron?
ohh and photocopy's of passports stored on the cloud, should I lose them, at least I can get home after some checks, made quicker, by the fact I have full passport details
@OP I wish you the best of luck with this, but I think your only true hope is that BA are very understanding with these 'events' and will re-schedule flights until this is sorted
