Was in line today at JFK terminal 4 regular checkpoint (alas, TSA apparently has decided I no longer am "safe enough" for PreCheck) for a Delta domestic flight. Two travelers in front of me had tickets for Emirates Airline. One had PreCheck; other did not. TSA "magic scribbler" told the one guy to go down to the PreCheck lane. When the second one asked if he also could go to that lane, the "agent" told him no because he didn't have PreCheck. The "agent" then said, "seems like they randomly give PreCheck to passengers of that airline; about 1/2 of them seem to get it." Guess TSA is now offering "free" PreCheck to foreign airlines but not as much to domestic airlines.
