2 passes that expire on 06/30/2016. United airlines lounges have free wifi, snacks, breakfast, showers (at many airports) etc. The one-day passes cost $50 but I am selling them for $20. You don't have to fly United to use the lounge -- you just need to have a valid boarding pass. I can deliver them at Stanford, or can meet in Mountain View, SJ downtown or Sunnyvale downtown. Price is OBO.
