I traveled on an international itinerary last December, DCA-ATL-CDG-BUD, and was not given TSA pre-check; however, I started two other European trips at DCA last year, all on DL metal, and was granted pre-check privileges (in late August, DCA-JFK-PRG, and in November, DCA-JFK-MXP).
On the December trip, I was on DL for the first two segments and then AF on the intra-Europe segment. I had to go through security at CDG to get first to the immigration officer, and then to get over to Terminal 2F to make the ongoing flight.
