I flew to NRT with a friend in march this year.

I bought both tickets over my credit card and yet when I claimed my points/miles I only received miles for my personal ticket and not my friends ticket.

Is that right? I mean, they could clearly see that both tickets where billed to my cc and so I generated 1400€ in revenue (I know, not exactly a fortune) and still they only gave me points for my 700€ tickets.
That just seems weird.

Do they really only "send" the miles for one's personal ticket?
Or have I been misinformed by the staff?

And how could one get all the miles?
Would it be possible for that friend to open a Skywards account for her and then to transfer those points to me?
Seeing that it's been in march (return end of april) it's probably already to late this time.
