I was aware that these rules apply if all legs on single ticket and not if there are separate tickets.
I meant stand-alone check-in. If it's one ticket, and you have an overnight break meaning you'd check in for a domestic trip (or one with no free allowance), they can't charge you.
Less than a year after USDOT promulgated that rule, I had a CA ticket LAX-HKG RT. On return I was stopping PEK for a few days. At HKG they tried to charge me according to HKG-PEK allowance.
