Is there any master threads that show experience by airport? Official policy is only apec card holder can use the lines, but i've found it's different depending on airport (and potentially agent).

SGN 2/23- single traveller- only issue is they didn't know their policy (I have a US passport/HK issued APEC card), and agent asked me for a visa. Told him i didn't need one, he sent me to the visa line, and after 5 other agents and 5 mins of discussion, I was sent back and through without issues. Exiting the country, they have fastpass for immigration, but unless travelling business, security is normal line
BKK 12/23- travelling with significant other- at first, they tried to tell me she couldn't use it- I asked nicely if he could just make an exception- they allowed it. Exit- they allow fastpass immigration/security
HKT 1/23- They have a sign that actually says ABTC + 1 is allowed- had no issues.
