Flights from the west coast are currently (as of June 11th) running $590(+tax) to Bangkok and $690(+tax) to Phuket international. The better travel discount shops have assured me that these prices will drop by around $70 towards the end of the month. The shops currently listed are not necessarily the best choices. I am still looking for a better fare.  I have not yet bought my tickets and would suggest holding off a little longer.

Note: Depending on the airline the tax varies.  Even though Thai Airways is cheaper, I believe you do not get to get off the plane in Japan, Something that is definitely worth the $10 extra.
