I must be missing something, as I cannot for the life of me find out how to book a multi city domestic journey!
For instance, I was looking for flights from Tokyo to Okinawa, then onwards to Nagoya.
I suppose this is an academic question now, as I found that two one-way tickets for each leg were very reasonably priced!
But for future reference, does anyone know how to book a multi-city itinerary from the jal.co.jp/en website?
