SXM was fine. We arrived really early so were able to get seats away from people both before and after checking in. All food options were available in both areas. When we arrived in Toronto we had to wait on the plane about 30 minutes as they were monitoring the crowds in customs. About half of the Nexus machines were out of order. They were passing out customs cards on the plane to Non Nexus holders. I would suggest getting one so that if Nexus is crowded you can use the regular machines. Safe travels.
