I have 2 seperate reservations
SQ SIN-DPS and then CO DPS-GUM and onwards, there is 3 hours between the flights, both are in business class

now assuming SQ will interline luggage (is it even possible at DPS to have transfer luggage?), will I still have to exit thru immigration (and buy a $10 visa)?

Anyone with DPS transfer experience, although I'd assume its not that common.

Thank you

i m staying in Bali on the outbound, thus only the transfer on the return
