Heres my problem:

I have a GLOB26 ticket ... DRW-xSYD-JKFx-Halifax-LHR-DAM-xBAH-SIN-DRW
I'm currently in Damascus working; contract finished 27 June.
Remainder of ticket if open.
BAH-SIN is on a QF flight number, but GF metal (only opion).
GF are suspending BAH-SIN at end of June, leaving only 2 dates possible for me 28 or 29 June.
28 and 29 are both "closed" ... I'm not sure if this no availability, or if GF are being very selective.
Qanats GSA in DAM (the ticket is QF) says GF "should fix it for me"
BA in DAM says same.
So far GF doesn't care (one of the reasons being that its a QF number, apparenly). I'm hoping I can convince the manager, who wasn't there today to help me ... either reroute at no cost OR put me on another carrier (I believe they have been doing this a lot)

Plan B is to up the milage and add some extra stoppovers in Australia.

Any thoughts ... esp before tomorrow ... grately appreciated.
