It's actually the main security line that will slow you down. Global Entry and PreCheck should help you make it, but you don't have a lot of room for error. Good luck
I seem to recall there being a separate security checkpoint for customs and immigration that was downstairs in the DL concourse. I certainly could be mistaken because I have no recollection of where you come out of it but I remember leaving something at a gate one time in MCO during the time of international arrivals and I was already by the train. I recall a security guard telling me I would have to re-clear security to enter the concourse again and to go down a set of stairs in the train station. It seems to me that there was a security checkpoint there. Is this used for international arrivals who are just transiting?
