Originally I read the thread title as "glamification" which made me wistfully recall the TWA RT IFC (Ambassador class) TATL award tickets that included a ticket on the Orient Express for 50,000 miles (plus an upgrade to IFC that I could use later on any TATL RT coach fare).

Under gamification, when I flew to Russia regularly, the cost in miles to upgrade the TATL RT (including connecting segments) from coach to "world" business class on PMNW (with KLM segments AMS-SVO and vv) was roughly equal to the number of redeemable miles I earned for the trip (and of course I also earned a ton of elite qualifying and lifetime miles on these trips). It wasn't rocket science but upgrading without guilt was nice.
