This is the first time I recall seeing a flight deal from the Bay Area to Madagascar with Delta Airlines tickets priced around $740 round trip on a few dates in December 2019. Most dates over the next six months have ticket prices from $1,050 to $1,600. Madagascar wet season begins in late-December. April to mid-December is supposedly the best season for Madagascar tourism.
