For all you frequent flyer lounge lizards out there, I recommend the website and app "Lounge Buddy": https://www.loungebuddy.com/. It will show you what lounges there are per airport terminal world-wide. And, if you register and enter your airline status and/or credit card types etc, it will tell you which you can get into. And, yes, it shows correctly that there are no lounges at SXM :-(
