I’m a HK APEC card holder and I checked Thai embassy in HK this afternoon.
1. Even if you hold a APEC card, you must be coming to Thailand from low Covid risk country, however India is of high risk.
2. It is not a visa issue, it’s a special circumstance with a Certificate-of-Entry to be issued by Thai Embassy AT YOUR LOCATION!
3. Chartered flight does not mean normal chartered flight, it’s specially arranged flight with special date, time, seat arrangement, safety measures and operated by designated airline.
4. For HK case, we need to carry out test 24 hours before flight, tested negative under accredited clinic, plus an insurance policy to cover medical expenses in case of infection in Thai.
