Tried below ports during May 2023.

TPE - possible same flight turnaround. I did not take same flight turnaround as wanna spend few hours in TPE lounge(but found it was not open since COVID). No need visa for turnaround pax, ground staff will wait outside the bridge and guide you to the transfer lane. CX488 - CX495

XMN - Same flight turnaround possible. Immigration and security check is required. Tried twice CX978-CX979 and CX970-CX973

CGK - Same flight turnaround possible. I also not tried the same flight as worried about to get through the immigration. Ground staff will also wait you at the bridge to guide you to the transfer lane to go back to departure area (no need pay 500IDR for the VOA)
CX719-CX798
