As to not open another thread along this same topic, just want to make sure I'm understanding the rules as I have flights coming up over the next several months that I booked optimistically hoping things would open up. If my current ticket is to HKG and I book another separate ticket, whether on miles or cash to another destination (say, Thailand), this would not be allowed? I've done this many times prior to covid and I've always had my ongoing boarding pass on me so I can utilize the transfer areas of HKIA. Even if I showed up for my flight in DFW to HKG with my second boarding pass already printed, the way I understand is AA might not let me on the flight b/c my connecting flight is not on the same PNR/ticket as my DFW-HKG flight?
