Yes he has to go Via domestic air port. there are internal bus services by airport authorities for international flight passengers... you wll also get cabs from domestic airport for international air port.. so no worries.. you can use any of services with nominal costs..

Within the domestic airport there should be a counter for hiring taxis, dont tell him to take a private rental car- no, a bombay taxi, prepaid and the luggage can also be taken along. If he is taking a flight like Indian airlines/Jet airways...I assume they do have bus services from domestic to international airport....you will have to call the particular airline and find this, or best option is to take a taxi - prepaid one from the airport ( as international airport is not far away from domestic airport). If he is taking Air India from Goa to Mumbai and then Mumbai to Cleveland, airindia should give him transportation, you need to call the airline directly and check that.
