This check-in area has bounced back-and-forth between T6 and T7 several times in the past two years or so. I think it depends what day/times you hit it. I generally go through there in mid-late afternoon/weekdays and, while the current T6 c/i area doesn't look great, I've had quick, efficient, often helpful service. As far as the elite security line, here the problem is that the space is not conducive to creating a lot of screening stations. Sometimes when I've hit the screening area, the elite line has not been open; but have not waited more than 3 minutes to get through the magnetometer. So, I'll take efficiency over looks; and in my experience it has been fast, since moved over the last time from T7. (Now that ["elite" c/i, not TSA] was a model of s-l-o-w.)
