eVouchers on Lufthansa (LH?)
website says eVouchers for their status members can be used for travel companions.

or SWUs....can anyone use their SWU to upgrade someone else? if so for which airlines? I know on UA the elites/1k can use their SWUs for other people even if they are not traveling as well.

I have no status. I am planning a trip to ATH next summer. I am doing a bunch of research to either a) figure out a way to make status by then, which is not likely, or any status that would help with the trip; b) figure out a way to upgrade on a trip to ATH using either mileage upgrades (with high probabilities using what ever strategy i can learn) or finding the "gifted" upgrades.

mile milage banks are on DL and UA (and trying to build CO in plans it will consolidate with UA)
