Newbie here. We're doing a side trip to Laos, flying with PG, at the end of our trip to Thailand in August. We will be flying back into BKK mid-afternoon and flying out on QR833 in J at 21.15. I know from reading the forum that PG don't check through international baggage anymore, and that the QR check-in only opens three hours before departure. Is there any way we can use one of the lounges before QR check-in opens?
