I have Pre Check with Delta, can it shift to Southwest?
Here is the background. I've been Delta elite for the past 8 years or so, most Silver, but a couple of higher years mixed in. About a year ago I started getting TSA Pre Check on all of my Delta boarding passes. I never paid for it, never filled out a form or anything like that. I sort of assumed it was a perk from Delta, since it never shows up when I fly anyone else.
So, here is my question? Do I "own" that Pre Check, when I fly other airlines can it come with me? I am asking in this forum because I have 6 WN flights coming up and really want experiences of transferring it to WN in particular.
If I can transfer it, any advice on how to do it would be appreciated.
