Hey Everyone -
My husband and I have spent the last few years mainly in Indonesia and after quite a few hours lost to the hassle of trying to book domestic plane tickets online on sites such as Traveloka and pay with foreign creed cards, we decided to write up a quick article about what we have found on the different travel websites and what solutions we have found. Hope this helps someone else or at least sparks a discussion on here to share ideas.
