What do you guys do when there are separate Sky Priority and Pre-Check lines? Some airports have just one priority queue with one TSA officer, who then points you to one of two different screening lines depending on the beeps. But other airports (DCA and CVG come to mind) make you choose between the two before getting to the TSA.
In DCA the two lines end up at the same place. What wasn't clear was whether PreCheck alternates or takes precedence over the SkyPriority lane. The PreCheck lane was much shorter last time I was there, only a single person in front of me.
Might have mentioned this before, can't remember. A recent flight I took was an Alaska flight booked through DL.com. When I checked in it asked for my traveller info. I thought for sure I wouldn't get the triple-beep but I did. Either the 72 hour window is not really that long, or Delta sent my info over.
