I am trying to build a Sapporo - Tokyo (2 night stopover) - Singapore itinerary in J class on JAL using the Alaskan multi-city option but the system keep returning messages that it is unable to find flights.

However, when i try looking for 1) Sapporo - Tokyo and 2) Tokyo - Singapore separately on the dates that I want, seats in J are readily available on both flights.

Does the free stopover not apply to 2 cities in the same country (Sapporo + Tokyo) or am I doing something wrong?

Will appreciate any advice here. Thank you!
