Any thoughts/opinions/experience would be appreciated.
Book as soon as you find availability. 100's [or 1000's?] of others are trying/hoping for the same. IIRC both UA & AA offer one way awards. You may have to do that or go on separate aircraft and/or days
Look in the UA & AA forum for threads on using miles (it can be confusing)
