Hoping someone can help me. I have an itinerary that I'm trying to book, and the ticketing airline is giving me problems.

Itinerary was valid on the Oneworld site and it let me make the booking. However, Qantas are claiming the itinerary is invalid due to it having 18 segments. Obviously, it was 16 on the OW site. My guess is they're counting BOS-LGA, JFK-LHR as 3 segments, whereas the OW site counted this as two. My understanding of the fare rules is that it talks about "city pairs" and therefore this should be two segments, as the system thought also.

Does anyone have experience with this and how was it resolved?
