Tin, I fully agree that the ACC noses aren't always clean. The only time we measure APP separations is when you transfer them to ACC, 6 miles apart, same level with 60 knots worth of closing. And I'm not pulling it from under my seat. Although I sometimes pull my seat back out after that.
Having said all that I said on this thread, I still think that the airlines are their own worst enemy. I mean, how much money does it cost us to watch traffic hold for twenty minutes or more? That's right, NOT A FU....N PENNY.
Open skies = open wallet.
