ticket price to san juan

Do you have any idea what a good price for a ticket to San Juan from Tucson would be? I know Phoenix & other big cities would be cheaper. But should I hold out for under $500 or a little over or is $650 a good price?

Without knowing when you are going, it is difficult to give you a solid answer.
