A bit of a rookie here on this: I have this flight right now... but that's because I was planning on staying in Amsterdam for a few days. Is it possible for me to make the connection I have on the WAY BACK through Amsterdam a stopover instead of a layover? If so, do I just need to call Delta or KLM? It would be the same price too? I'd like to save the $80 intra-Europe flight I was going to book.
