I have an upcoming IXE-BOM-DEL flight on Air India, and called in to enquire about any increased baggage allowance.

I was referred from the booking call center to their Mileage department, who first told me that I would have to check with United, since they don't have all the updates. On pressing further saying that Air India is advertising their entry into Star Alliance widely and also is promising benefits to its fliers on other Star carriers and that she should check again, she puts me on hold, and then comes back with 'United is not part of Star Alliance right now'!
