My latest shtick (correct at the time I pressed the "post button"), was adding a frequent flyer program number to a booking, and card holder would get credit for it, works by people who only have a last name and same gender in common. With star alliance that is.
As I realise that a family with 10 kids, each flying once a year would make it a gold card, meaning, that DD will stop functioning out of sheer bulk mails being pm'ed to me, I would need to set a price for it.
Any suggestion what would be fair to ask?
I actually need to makes some calls for it.
