Do you need to go through immigration if transiting/connecting international to international at Penang airport? Looking at doing a turnaround flight, sq from sg back to sg on same plane. 1 hour from 11.15 arrival to 12.15 departure. Sg passport. No luggage.

Saw a sign about transfer desk on airside on a youtube video but the sign suddenly disappeared midway and only leads to immigration arrival. Any info would be appreciated as not much can be found online. Thanks in advance.
