I've been trying to make a booking for a few days now. The Oneworld tool keeps switching to the Global Explorer fare during the planning process, even though the Oneworld Explorer fare was shown as valid before. Most of the time, I even see the Oneworld Explorer fare at the bottom. All flights are showing as valid, but still I get a message saying "Your itinerary exceeds the 34,000 mile limit on a Business or First class booking. To finalize your itinerary, please reduce the length of your trip."

Is this something that's known to cause problems? Any ideas on how to get around this? Is this jumping between fares something that's known to happen with the online tool? I made sure I've not included any flights with non-OW airlines, so it's probably not an accidental codeshare. Ideally, I'd like to book via the AA RTW Desk or with British Airways, but I just want to make sure that my route is bookable. The online tool is great for testing out different possibilities and options. I'm currently trying the route OSL-HEL-DEL-HKG-CMB-HKG-DPS-HKG-CTS-HND-HNL-ANC-LAX-JFK-MAD-OSL because I want to book the overwater with AA or BA.
