Fantastic, thanks for the clarification. I think my only other question is can you change either the date or the destination of the final leg after the LAX stopover? In your example, I may not know for sure when I can do the LAX-SJU portion until we get closer to the date of that flight. Also we may prefer to go somewhere else when it gets to that time, or may not be able to go at all. Is there anything I should know about changing the date, destination or canceling that leg altogether?

Thanks so much! ^
