Our flight going to SXM on Nov.1 was totally full and the same returning in December.There was not an empty seat on either flight.When looking at the flights online and even when you call, you are often told the flight is full with Westjet as they never over book their flights and always leave a few seats which can be booked for last minute travel or emergencies. We know this is true as we have been fortunate enough to get some of these seats.
