I am taking BOM->SFO AirIndia flight connecting through BLR. BOM->BLR is AI639 departing 9:25 am February 8,'24. BLR->SFO is AI175. It is a single ticket. I am assuming I will be able to check-in baggage through to SFO in BOM at T2. Is that true?

I am considering taking a flight AMD->BOM on Indigo or Air Vistara, arriving in BOM T2 February 7th around 8 pm. Can I check the baggage early at AirIndia T2 for the next day morning flight? If yes, is there a way to hand over luggage at T2 domestic arrival for the Air India flight, or do I need to get the luggage over to international departure? Is there a place to store the luggage if it can not be checked in? I am traveling AI business class. Is there a preference between India and Air Vistara in terms of convenience in the transfer of luggage? Are there Airport services I can use? On the domestic leg, I will be flying premium / business.

Thanks in advance.
