All airline ffp's have partner airlines. As above need details of your flights.

USA based airline ffp's tend to be more generous (status benefits/earn/burn/upgrades/award cost/award cash surcharges/expiry) compared to non USA based airline ffp’s. (even after the recently announced changes to some USA ffp’s)

The airline you fly most or an airline of the country you live is the best ffp for many people.
The airline you fly and the airline ffp you credit those flights to does not need to be the same.
Freq flyer miles are not equal to earn or burn.

You will not fly enough to get status. Upgrades are helped by status.
Upgrades on non USA airlines are very different to USA airlines. With non USA airlines always expect to fly in the class you buy.
