Membership Rewards points can be used for award travel on every airline which is a member of OneWorld, Skyteam or Star Alliance. Which airlines do interest you?
The Use Points for Charges rate is poor value. To offset $716.32 I would need to redeem 119,387 points. That's $0.006 per point.
I'm new at this so I need a little help. I see how I can transfer to Delta from Membership Rewards but how would you get flights on American or United. I know they are members of the alliances but how do you book the US flights?
