The one April last year was for everybody (it was not targeted though they didn't email everyone about it) and runs for flights through to sometime in mid-April this year. You just had to register and make bookings during the booking window. The targeted 50% bonus offers come up more regularly (typically mostly for different people each offer though).
Got double SC and an op-up for a domestic flight just recently. A business class seat with half the SCs one would get if one bought a business seat normally and at a fraction of the cost.
