I think I've solved this air problem for my cruise- I believe I can use 80,000 British Air miles for a Bus. Cl. ticket on American Airlines - Miami to San Juan to embark the ship - then Santiago to Miami at disembark (use the ship's transfer from Valpariso to Santiago - @$49 )Best I could do ---Hated to use my BA miles, I was saving them for another trip - but couldn't find any other way to do this using my accumulated mileage in Delta or Continental. Thanks for your help! Renee
