Interisland flts are cheapest with UA miles. Only 6K o/w. AA & HA require 7500.
What airline is "SA"? Or is that your abbreviation for San Antonio (SAT)?
Great gift, IMHO.
If you decide to xfer UR to UA combine them first. That way they call all go into one UA acct. UA First Everyday awards are 180K each r/t. So 360K total. Then, you may not have ALL segments in First. Don't think I would do that.
