@matigo Thanks! Yes, that covers all my questions… They don't want to exit the airport. They're just looking for a cheaper flight to Seattle and it's cheaper through this ocean than that.
I'll tell them about the airport maps thing, though the main concern is only about getting from one terminal to the next, so I guess your information helps there!
They'll probably start out of India with International roaming. It's gotten cheap enough in India to enable it for a week for emergency calls.
I assume you mean to say that the airport doesn't have free wifi? It's ok if it doesn't…
