San Jose, California SJC to St. Lucia UVF in the Caribbean is a wide open sale today with American Airlines and Delta Airlines low fares from $380 to $440 available for many dates from late May through mid-December.
Delta Airlines has a $380 fare for San Jose to St. Lucia, an island known for its luxury resorts. That fare earns 50% miles with Alaska Mileage Plan. An American Airlines fare of $434 is also available today and earns 100% redeemable miles for the 8,000+ miles routings.
San Jose SJC – UVF St. Lucia

The $53 ticket savings for Delta is negated by the overnight. I looked at a couple of different routings and they all required an overnight on the return with the $380 fare. You can earn Delta Skymiles on a $262 base fare or 50% Alaska Miles on Delta V fare for 4,227 redeemable miles.
American Airlines looks like a great deal for St. Lucia is what is normally a high priced route to the Caribbean.
