Applied for Precheck 3/28/17 in the evening.
Scheduled my appointment at BNA for the next day 3/29/17 in the morning.
Appointments were wide open.

Received a letter in the mail with my KTN after about a week and a half (letter dated 4/6/17).

When I checked my status online around 4/3, it said "Eligibility Determined" but I did not see a KTN until about a day or 2 later.

I googled to see if that meant I was potentially denied, but I saw somewhere that if you were denied, it would not say 'Eligibility determined." Not sure if that is how it works.
