Route syd-sin-lhr

IN REAL live there are some routes that are there and let pax join the flight or just a segment. please implement these rules as for Australian airlines this is a must.

Routes like SYD/MEL SIN CDG/LHR/AMS and others or DPS-SIN-AMS CGK-BBK-AMS also excist in real live there are many via SINGAPORE flights with pa connecting both ways.
It would be good to implement.
EU examples like DXB-FCO-JFK or DXB-MXP-ORD also excist.
What can we do on these routes.

I have flown MAN-MUC on a Emirates plane that was on route to DXB. Bought the ticket MAN MUC

AirlineSim does not model individual bi- or multi-lateral air service agreements, which all of the examples of 5th Freedom ASAs you listed are. There was an in-depth discussion about a related topic recently, if you’re interested: Revamp of EU traffic rights

Understand, maybe something for future roadmaps….
