I have a ticketed OW J award BKK-AKL-BKK on a mix of MH, CX, and QF QF in late may. Specifically

BKK-KUL(MH785)-HKG(MH432)-AKL(CX197)
AKL-MEL(QF156)-KUL(MH148)-BKK(MH796)


I travel in about 1 week, and when reviewing the various sectors on ExpertFlyer I noticed the tha final sector KUL-BKK MH796 22:15-23:20 wasn't showing at all. I tried a dummy single sector booking on MH's own website and again the flight is not listed as operating. The flight seems to operate until May 28, then ceases thereafter. The next available flight is teh following morning, and there is some J availability - but this requires an overnight in KUL, and loses a night in BKK.

This trip has been a nightmare due to mis-handling by USDM (who failed to ticket correctly), resulting in a cancelled ticket, leaving poor options at short notice with AA once miles were re-deposited.....I'm almost tempted to cancel the whole thing and buy a Y ticket!

Assuming that MH have elected not to operate this sector, is it AA or MH who should advise me. And as a follow-on, should MH provide acommodation at KUL since there is now a compulsory overnight? (similar to STPC?).

What are AA's obligations since they issued the ticket? What if I decide to cancel based on the overnight in KUL not suiting? Grateful for opinions/experiences.....Note I have yet to contact AA or MH as I'm keen to gain for some idea of my options.
