However, when exiting the mainland, show mainland departure immigration the direct HKG-USA flight. Departure immigration may not allow a HKG-TPE-USA routing.
4. Once in Hong Kong, cancel the refundable HKG-USA direct flight. Check in for HKG-TPE-USA at Hong Kong airport normally. Hong Kong immigration will not care about taking the HKG-TPE-USA flight.
Adding a data point confirming that this works.
In step 3, did not have 港澳通行證, so needed a flight out of HKG within 7 days.
In step 4, flying HKG-TPE direct with the intention of entering TPE (not transit) had no issues. Used 入台證 with PRC passport to enter. Did not have 大通證.
