Just had a peek at the Malev site and if what I am reading is correct, not only is their top tier invitational only (yet at the same time provides a number of status points required to reach the level) but also seems by far the most difficult in OW.

For example, it would take 80 short sectors in full Y to hit ruby (500 awarded per sector to reach 40K) whereas most other OW programmes would have awarded you with Sapphire by that stage. 80 sectors in full Y on CX at least would give you their top tier (assuming you were CX Gold in the previous membership year).

Seems that Malev have gone out of their way to make all of their tiers pretty much unachievable.

Unfortunately the RJ website does not give much away on how you earn their tier/status points or miles so can't comment on them at this stage.
