We are planning a trip to Seram and West Papua for birding next year. Our flights from BNE-DPS will be award tickets on DJ, then we have to get to the following places:

DPS-Ambon
Ambon-Sorong
Sorong-Manokwari
Manokwari-DPS


It looks like the airlines we have to choose from are a hodge-podge of Lion Air, Wings, Batavia, Express and Sriwijaya. We will probably have to use SUB or UPG to transit between DPS and Ambon, then Manokwari back to DPS. This thread is a couple years old so I was looking for more recent experiences with these airlines. Not fussy, just want to get there reliably, safely and preferably be able to book and pay online. There will be a buffer of 4 days in Bali before out flights back home. As far as I can see, overland transport doesn't seem to be an option between Sorong and Manokwari.
