There was a huge line for economy passengers to check in on Thai Air at Denpasar but thankfully we were in business and had no wait. She confirmed they do not do online checkin at DPS airport so would have been great if the mobile app were updated. Lounge was super crowded and air conditioning basically didn't work, but the airplane was new and beautiful, and service was excellent. No priority lines at security for business that we could find. Hope this helps others.
