I flew into LAX in March and had a priority Tag from check-in for Plat status. Got through LAX Customers in 5 minutes, waited 45 minutes for my bag along with several others who were in business class and 2 couples from First. Watched most of the plane pick theirs up and continue through. To say I was lacking in happiness is an understatement.
That was the only time I've checked a bag this year.
Last year I checked a bag going to Vienna, Again, Plat status put a priority tag on the bag... It showed up in Vienna 2 day's later!
