I'm on one at the moment; the 'old' KLM/NW/CO/MH/etc RTW program that earns miles for Skyteam on a lot of flights. You should look into it if you want to travel around the Pacific, since you can use Continental Micronesia, Air Vanuatu, Air Calin and some more... or Central Amercia with Copa Airlines. Look for rules using the YRWWJ40 or CRWWJ49 fare codes on google.

This is NOT a RTW from one of the alliances, rather a separate Round-The-World alliance. A lot of Skyteam airlines in it (though not all at all)
