Thanks! Flights to SJU are usually cheaper than other places in the Caribbean or on the East Coast. The goal is to get 220 Tier Points in each direction around $2 USD per TP or less. This can usually be achieved by flying something like LAX-PHX-PHL/JFK-SJU or SFO-LAX-PHL/CLT/MIA-SJU

If you just fly Los Angeles to Miami and earn 140 TP's that's usually quite expensive.
