So you cannot earn Skyteam miles on this route but you can redeem Flying Blue miles on PG (but be prepared to give a lot of miles : 50,000 miles on FB for a return BKK-REP).
In fact, Vietnam Airlines, a Skyteam member, also will ticket the BKK-REP route. But it would cost a bit more and involve a stop/plane change in Ho Chi Minh or Hanoi, doubling or tripling the travel time on PG.
