I have collected a quantity of points on skyteam - but these are spread over 4 airline programmes.

Does anyone know whether I can collectively spend them in one lump - i.e, 10,000 continental points plus 15,000 alitalia points? and thus redeem them on one ticket?

Does Skyteam have one membership programme for all member airlines - thus adding all points earned onto one account?

I did check skyteam website but did not find the solution there.
