An obvious example is as follows...
I'm a UA Premex and a LH FT.
A couple years ago, LH had a 2x miles offer for your first USAir flight.
They also offer 3x miles for travel in F class... all counting toward status!
They also had back then a 1000 mile minimum for partner domestic legs.
USAir had a SFO-FPO First Class offer of $600 all in with 4 legs each way.
So...
For $600, I got around 70,000 miles, with enough EQMs to requalify for LH FT again. On UA, I wouldn't have even bothered, the payout would not have been worth it, around 12,000 miles total.
