Yes, all that. The round the world journey my friend Paolo undertook earlier this year is quite the read.

Besides two extraordinary business stops out of the RTW route, playing with OJ (Open Jaw I/II), MAM (Maximum Allowed Mileage), UF (Unpublished Fares) and other black magic hacks, the whole cost has been contained under the cost of 2 average round trip coach tickets US-EU. 

And 90% was done on Delta and its SkyTeam partners. Quite the way to cool off the entrepreneur life. I'm very jealous, Paolo.
