Have run a few searches on CDC's but haven't found an answer to this particular question, hope someone here can help 
Steve & I are planning a long weekend in Provincetown in Aug/Sep and have accumulated enough miles to pay for UC rewards. G availability is OK on the dates we're looking at. We'll do what we normally do and shed out 20K miles for two x CDC transfers here in UK. Normally we only use the CDC between home and LHR but as VS offer to take you to any address in MA, CT or RI from BOS under the rules of the CDC, spending 20K miles to get ourselves from BOS to Provincetown and back sounds great value. Sorry to ramble...and so to the question....can our friend who will be flying up to BOS from DFW hop into our CDC and get a ride to Provincetown and back with us?
Thanks
James
