Any ideas on it, noting it also didn't appear on the list?
Thanks!

Those flights were cancelled on 4 July as part of a rolling reduction of flights to India from now until October. Other cities get reductions in September (HYD, BLR, MAA) The guidance says that passengers on these flights were supposed to be rebooked either automatically or via their travel agents as thus:
Rebook onto British Airways (BA) or Qatar Airways (QR), Lufthansa (LH), or Swiss (LX) from any UK airport to BOM and BOM to any UK airport. Rebook into lowest available in same cabin, or lower cabin.
Either way it should not be a surprise today, but it isn't in my list due to the fact that the cancellation happened 10 days ago.
