cash for travel needs

[Mano]

my parents are travelling from chennai to dc via frankfurt and then Charlotte. How much cash would they need in their hands to handle any emergency? Planning to take some travellers checks.. would they also need any cash?
can you suggest some amounts? thanks

anything between 30-50 dollars is enough
