I booked with Delta a flight ATL => FLR. The return is KLM codeshare through AMS arriving 9am on a Saturday, departing 5pm for ATL that same day. I am wanting to catch taxi or train to City Central and spend several hours. I plan on carryon only but there is a possibility (depending on shopping) that I may check my luggage. Even if only carryon, I will use the left luggage at AMS. My questions: will KLM/Delta check my baggage through to ATL? and will I have to go back through security at AMS? I want to know exactly how much time I have in Amsterdam. Any other recs/advice would be appreciated. Thanks.
