3825554 - Why are we getting a higher fare when Concur Travel splits the tickets for two airlines?

When a user tries to book multiple airlines, for example B2 (Belavia Belarusian Airlines) and LO (Lot Polish Airlines), Concur Travel does an extra search where a lower fare should be displayed. However, Concur Travel is displaying a higher fare for split instead.

When users try to book multiple airlines using Split Ticketing, the fares are higher when compared to a single ticket. , KBA , CON-CA-ADM , Administration , CON-CA , Cross Applications , CON-SRV-TRV-ADM-LAN , View Airlines , Problem
