This might be a newbie question. I have a trip in May booked on Delta (BOS-AMS-BOM / BLR-AMS-BOS), where one of the four legs (BLR-AMS) is operated by Jet Airways. If Jet goes out of operation, or otherwise cancels this flight, what will happen -- is the onus on Delta to rebook me somehow, or am I going to be on the hook to figure out an alternative? Not sure how it works in such cases where it's not Delta's "fault" - but on the other hand it is a ticket issued by them...
