Southwest Airlines San Juan Operations

In the last few months Southwest started flights to SJU from most of its bases. A couple of weeks ago I saw they had a flight from HOU to SJU but as I went to book the flight earlier this week I noticed its no longer listed on their website. Does anyone know if this is a seasonal flight or has it been all together cancelled? Thanks.

The Nonstop appears to have ceased. There is a thru flight HOU-BWI-SJU.

It reappears March 7 operating Saturday-only as far as I can tell.
