i believe so but i'll have to double check. kiwi collection is owned by signature travel which is similar to virtuoso. i know with virtuoso and hyatt that we earn stay and points credit when i book hyatt with a virtuoso agent.

all of this i learned from reading the luxury forums here and after pm'ing the hyatt gp concierges in the hyatt forum (regarding virtuoso bookings).

I pm'd starwood lurker. will let you know what i learn.
