I assume you'll be on Blue Manta? We'll miss each other by a few days. I'll be in Raja Ampat also on Mermaid 2, from 4 to 12 December, 2022 (in late December to early January 2023, I'll be on Infiniti, South & North Visayas, Philippines).
I booked Batik Air, nonstop Jakarta-Sorong, leaving Jakarta on 3 December at 00:35, arriving Sorong at 06:40. A four-hour flight, instead of a 24-hour one as mentioned by
@Manneca in previous post. I'll stay in Swiss-Belhotel for a night before boarding on Mermaid 2.
Fingers crossed, Batik Air has been good to me in August. Leaving at midnight would usually be on time. If there's a delay or cancellation, I have the whole day to find an alternate flight that would take me to Sorong by 4 December noon.
Tiket.com also let me purchase the tickets via my US credit card.
