Now that Kenya is a country in Africa that allows 2 entrances to Europe, I wonder if the following is a valid 5 continent routing. I never really understood this exception. Also I can’t use the OW validator at this time.
NBO-LHR-HKG-SYD-HKG-asia segments-LAX-usa segments-LHR-europe segments-NBO (transit in LHR & HKG enroute to SYD)
