Indigo Reschedules flight just 12 hours before, What are my options

Hey guys,

I booked a trip from Melbourne → Singapore → Bengaluru through IndiGo, all under one PNR. The first leg (Mel–Sing) is operated by Jetstar, the second (Sing–BLR) by IndiGo.

Got an email barely 12 hours before departure saying my Melbourne flight’s been pushed by 48 hours. That obviously screws up my connection to Bengaluru.

Since the whole thing’s under IndiGo’s PNR, does anyone know:

Can I get a full refund for the entire trip?

Are they supposed to put me on another airline if I can’t wait two days?

And if I’m stuck here, do they cover hotel/meals?

From what I read, DGCA rules say if a flight’s rescheduled by more than 2 hours on an international route, you can either take a refund or free rebooking. Just not sure how that works when one leg’s operated by Jetstar but booked via IndiGo.

Anyone faced something like this before? How did IndiGo handle it?
