So I'm given to understand that the following "scheduled charter" flights between Taipei-Taoyuan and Ishigaki (Japan) exist and are open to the public:
AE7334 TPE1140 – 1335ISG E90 36 AE7335 ISG1430 – 1425TPE E90 36
GE686 TPE0900 – 1055ISG 320 47 GE685 ISG1200 – 1200TPE 320 47
However, I'm unable to check prices/availability for either on the respective company websites, much less book online, and my usual stalwarts (ITA Matrix etc) don't even acknowledge that these flights exist. I'm even having trouble confirming the dates of operation. Are there any Taiwanese (or other) travel websites etc that would have this info? English/Japanese preferred, but I'll can puzzle out Chinese if needed.
My ultimate goal is to get a price for a SYD-TPE-ISG-(NRT/HND)-TPE-SYD loop, but I'd like to understand my options first.
