I know you can book AA flights using BA Executive club miles. I'm trying to find a Star Alliance partner which accepts AMEX Membership Rewards (i.e ANA, Singapore Air, Air Canada) and will allow me to book domestic flights with Continental or United. I understand ANA's system doesn't allow it, but would anyone know about Krisflyer, or if there is a way to use aeroplan miles to book on Continental flights?
Thanks for any help
