xONE3 or xONE4 ?
I know that if an itinerary goes SWP to Europe via Asia on a single plane service it is treated as 3 continents, BUT is travel from South America to Asia via North America with only a transit counted as 2 or 3 continents.
For example: BKK-LHR-GRU-JFK (transit)-HKG-BKK. Would this fit the xONE3 and not count NA as a continent?
