I am not sure that I understood what you did, Claudia, and perhaps Frank can verify it:

He said "Should the EMBARKATION port...."

Does that include debarkation port as well?

Also, he did not specifically state that he would take care of all airfare, regardless of how you booked it, through Oceania or on your own.

Perhaps I am nitpicking, but it would be a comfort to know his exact response.
