with a 24K max a year that is a lot of "familly member" for 2 F ticket US to EUR?
most award to Europe are going to be LH (10,000 miles extra per sector) therefore even with the miles+cash on LH you need: 125000 + 20000 (or 40,000 not sure)=1450000 @ 24000 per "familly member= 7 new accounts. I am not sure how many accounts you can open for "familly members" and buy the max of miles before raising red flags...
Any taughts?
