They are talking about
cabin bonus, aren't they? Not status bonus, which up the top they say remains unchanged?
No in a simpler and fairer manner what they have done is changed the figure used to calculate Status Bonus Points for example the bonus points earned when flying first was calculated on the First class earn so to keep it simple and fairer lets say that was 1000 base points. silver would earn an extra 500 points Gold 750 and Plat 1000 where as now the bonus rate is based on a different number ie if first class 1000 points however if flying economy on same flight you would earn lets say 500 points and silver an extra 250 Golds 375 and plats 500.
Now if flying first you would earn 1000 base points plus as a plat an extra 500 points based on the Economy rate
so before flying F would earn you
Base Points 1000
Staus Bonus Plat 1000 Total 2000 points
Gold 750 Total 1750 points
Silver 500 Total 1500 points
New Earn on same flight would be
Status Bonus Plat 500 Total 1500 Points
Gold 375 Total 1375 points
Silver 250 total 1250 points
Seems simpler and fairer to me
