Just found this nice deal on portuguese version of eDreams:
Open jaw ticket means you arrival city is other than your departure city. From Paris CDG to Jakarta and back from Bandar Lumpung, which is just about 250 km far from Jakarta. There is a stopover on both ways in Dubai where you can stay up to 11 hours! What’s more, the flights to and from Dubai are operated by Emirates Airbus A380, which is the biggest passenger airplane in the World.
Flight from Bandar Lumpung to Jakarta is by Garuda Indonesia. Very important: you must take this flight otherwise your ticket will be cancelled because of the no-show rule!
