This means you will not be able to use multi-city to book a one-way with stopover inside the end of schedule bug window and if you really need a specific date for the TPAC segment then I would probably book that first and look to add the BKK-TYO segment once the TYO-US segment comes outside the bug window. You might be able to do it online if you are gutsy and it might work out better than having an AS agent add it since that might trigger the divorced segments. To do it online (which I haven't tried in a couple of months) I think you would have to select to discard your current flight to make the change. This won't actually discard your current flight until you confirm the new change, but I don't know if you can use multi-city when changing flights which you definitely will need to do to bypass the divorced segment restrictions. If you have to go through an agent to add the BKK-TYO segment I would first try to get it added on the date of your TYO-US segment and if that did not work then have them add the segment the day before (creating a 1 day stopover). Once you ticket the itinerary with the 1 day stopover you then hopefully can use the online change tool to change the date of the BKK-TYO segment to your date or online change with multi-city if that is an option for online change, and if online does not work then call an agent, telling them you just want to make a date change on the BKK-TYO flight to the next day.
