There were some discussion about rule interpretation.
AMS-HKG-SFO-LAX-LIM-xMIA-LHR-AMS
is valid.
There was discussion about
AMS-HKG-SFO-LAX-LIM-xMIA-xPHL-LHR-AMS
(arrive at MIA from departure from PHL < 24 hours)
North American transit exception can be applied for combined two transit points ?
rule:
(e) Only one intercontinental departure and one intercontinental arrival permitted in each continent except as follows:
1. Two permitted in North America when one is a transfer without stopover.
Then, how about
:
LIM-xMIA-ORD-xPHL-LHR
Still, xMIA is 2nd intercontinental arrival without stopover, xPHL is 2nd intercontinental departure without stopover.
