Travelers going to ETHGlobal Singapore flying on a star alliance carrier can hit me up for a free class upgrade (while my supply of miles lasts!)

This is awesome. How does this work? What point / loyalty program are you using?

/dune co-founder and wartime cto.
founder mode on /founders.

you should join /climbing if you climb.

Sweet. I've been using Eurobonus (SAS, now Skyteam) and Miles&More (Swiss) and the former would let me personally upgrade with points, but the latter doesn't seem like it allows for it. Much less random ppl on the internet.

MileagePlus (United Airlines). It offers two upgrade instruments, traditional miles and PlusPoints.
