not necessarily....i end up taking 50+ flights on 9w every year but i always credit those flights to dl....it helps me maintain my dl diamond status which means a lot more to me than getting platinum status with 9w....the downside is that i don't get any elite benefits when flying 9w but i am mostly flying in business class so it doesn't matter anyway....
