Haha start of the year I flew, with 7 other people, SFO-LAX-BOS-DFW-HKG-DFW-SFO in the span of a weekend for $1000 ^_^ walked away with 60,000 mi, top-tier status at American thanks to a now-defunct promo, and 10 systemwide upgrades (each). If you enjoy the hobby, there's really nothing better.
Then, later in the year, I redeemed 75,000mi per person for a round trip in Etihad Apartments to the Maldives ^_^ Both the earn and the burn side can be a great time.
Going back to Hong Kong later in the year, paid $2200 for a round trip business class ticket on AA from DFW-HKG, upgraded to first and thanks to 3 stacked promos, earn 70,000mi and that round trip alone gets me 1/3 of the way to EXP status for next year.
