Take on the multiple express check in lines.

Nothing has improved travel more than PreCheck, Global Entry and Clear. It's amazing how much time and aggravation this has all saved but with so many people signed up for it, it's now becoming a bit of a dance to decide which of the express lines are best. I recently added the virtual ID thing which is cool in that you don't have to take out your ID but is odd that it is itself another line.

Today I was told to go for the virtual ID line and all of a sudden realize that the line I'm on was busier and thus actually slower than the pre check one. It's like Russian roulette of airport lines trying to decide at this point.
