Hope someone can advise me. Have two upcoming flights on Garuda not very long just Jakarta to Makassar return.

Am Marco Polo Club and tend to stick to Oneworld, and Mileage Plus which is used on occasions to fly SQ and TG. Neither of which have an affiliation with Garuda.

Am curious as to which programmes GA are affiliated with and is it worthwhile joinng anyone of these. All suggestions welcome.

Did do search on this site but turned up nothing.

Thanks.
