I recently booked an asia trip using points and adding stopovers. Technically speaking, I have no stopovers left to add to the trip, but given that a stop-over is classified as 'over 24h in a city' I'm wondering if I'm able to add extra Alaska legs to the end of the trip (ending in LAX) and how to convince the rep to do that (and if it's possible to make sure there's room ahead of time)?
