I'll be flying from Kenya to Singapore next month, transiting Mumbai. these 2 legs are bought separately from 2 different airlines.(Kenya Airways & Singapore Airlines).

After arrival at Mumbai, is there a transit counter where I could get the boarding pass for my connecting SQ flight to Singapore? Without the need to clear customs since I don't have an Indian Visa.

Based on my google, seems like there's no transit counter?

Thanks in advance!
