Looking into a trip to Europe this holiday season. Italy is high up on the list, as is London. I'm an Amex Plat and Biz Gold member, will have about 150k points. Live in San Diego - I know we have a direct to London on BA. This trip is for 2.

My question is - what is the best way to utilize MR points to get to Europe? Best airline to transfer to for Miles? Also - how does the international companion ticket work?

thanks.
