India domestic flights to carry same baggage as international flights [closed]

I am planing to book ticket from IAH(Houston, TX, USA) to BOM(Mumbai, MH, INDIA). My final destination is AMD(Ahmedabad, GJ, INDIA).

I did this before, booked domestic flights from AMD to BOM and change airport @ BOM and then catch international flights. GoAir has policy For Customers travelling on an International flight. Its still there on their Terms and Condition Page, If you have internation flights in 24 hours of the GoAir flights, then they will carry same luggage as internation without any extra baggage charge.

But when I called customer care to verify this, they told, its there in website, but now they are not supporting that :(.

I want to know, is there any other carrier in India, which carry same luggage if we have domestic flights in 24 hours of internation flights arrival or departure?

If there is no carrier do this, then which carrier will be cheaper for domestic with luggage ?

I check online, like JetAirways charge 500 Rs per kg, and GoAir charges 250 Rs per kg.

This will be expensive for 6 bags with 23 KG each.
