Just wanted to say that I booked plane tickets on Lion Air through Perama Tours in Bali (it seems that most Indonesian airlines don't accept U.S. credit cards), and they were extremely helpful and reliable. They responded quickly to every question I had. Then, when I had to cancel our trip due to a work emergency, they actually got some of our money refunded and sent it to me using PayPal! I am so impressed by the staff -- they are polite, efficient, and great to work with. I usually buy airline tickets myself online, but since this was impossible for internal flights in Indonesia, I'm glad I used Perama Tours.
