Costa Rica Airfares

[Traveller]

Holy Crap, Batman!
Now I'm used to paying anywhere from $700 to $1,000 to fly from Fresno to Cali. I've got an offer to go to Costa Rica and do some work. So, I was looking at flight costs to San Jose, Costa Rica.
Check this out (Jan.11 to Mar. 01, 2005:
American Airlines
Fresno Air Terminal to Juan Santamaria Int'l (SJO)
San Jose, Costa Rica
Adult     1  $374.00  
 Sub-Total  $374.00  
 Tax  $67.50  
 Grand Total  $441.50  
 This Fare Includes All Fees & U.S. Taxes  
To Me this is wonderful.
If I leave out of LAX:
Adult     1  $253.00  
 Sub-Total  $253.00  
 Tax  $55.00  
 Grand Total  $308.00  
 This Fare Includes All Fees & U.S. Taxes  
Just keeping an eye on fares. Alternatives, alternatives.
