Thanks for all the help and I may contact you if the need arises. I searched all the Delta q&a to no avail. This should not be such a mystery to newcomers to the wonderful world of Delta. We also found an old Pointsguy article which pointed us to the award chart amounts. Kind of funny that they price flights one way but you must go roundtrip. With my wife's permission I will try and book Monday. If there is a God next March we will see pyramids in OAX and later snorkeling in HUX.
