Hi to all, hope I am the right forum. Does anybody have a link or document that summarizes possiblities of transfering/exchanging/combining miles between airlines and or hotel partners. I would like to use up some hanger on miles for a reduced travel EZE-MIA-EZE. Something like the old AA/US Airways promo where you could use US Airmiles mile on AA segment and vice a versa.

I have some hanger on miles I would like to use up. Below is a example.

Starwood - 4439 Miles
Hyatt - 5197
Hilton- 2500
DL - 16944
MX - 15550
UA - 11745

Miles I don't really want to use except for emergency:
AA - 480K
AMEX - 160K
MAR4IOTT - 130K

Thanks in advance.
