to those who have Pre from another airline:
do you get the 3 beeps even on last minute bookings?
I have some trips this weekend but they were booked 2-3 months ago. One is business select, so I'd consider cancelling and rebooking. However, I'm wondering if only trips made a minimum of 'x' days/hours ahead of time get sent to the TSA for Pre.
The TSA should give out their own prepaid invites for Pre: to the people like me who opt out twice a week and waste their time with 'no alerts found' continuously.
