Delta & TSA Pre-Check
I'm interested in getting TSA Pre-Check to make life easier at the airport. I see that you first need the invite from the participating airlines, of which Delta is one. Does this invite come from Delta directly? And is Delta only sending invites to certain Medallion levels (Diamonds/Platinums or just Diamonds) or are they extendeding the invite down to Gold and Silvers as well?
EDIT: I do know you can also get TSA Pre-Check after being cleared for Global Entry. However, I haven't traveled internationally in over four years, don't forsee doing any frequent international travel in the next few years (maybe one or two trips in the next couple years). I also do know military members with proper ID Cards are automatically eligible to use Pre-Check, but it's only at certain airports.
