I tried searching but couldn't find an answer....
I'm planning a DONE3, and when using the OneWorld booking tool, once I get into the flight selection screen (after it tells me my itinerary is valid) it is telling me that a maximum of 5 stopovers are permitted on itineraries under 26,000 miles (I have 8). Unless I'm blind, I don't see this listed in the actual rules document and I don't see that listed in the wiki. Is this a tool bug or is this an actual rule?
