Back to the original post, Sunwing is mainly a package vacation operator, though you can book flights only.
So far they only have two destinations in SXM - Ocean Point and Sonesta Maho
So Kudo's for scheduling wkly flights with only 2 packages to pick from as that is their traditional base

For those who leave via Toronto, lots of winter options, non stop everyday but Monday - 8 per wk
Air Trans - Sat
AC - Wed & Sat
WJ - Sun, Tues, Thurs & Fri
Sunwing - Thurs

Plus lots of flights that connect trhu the US
