Not only immigration, but also check-in.
One way to solve that is by creating another entrance/exit point on the opposite part of this theoretical klia2B. Can check Jeddah new terminal masterplan for a similar concept.
Doing this actually opens the possibility of having a different operator (not MAHB) operating klia2B
White is Phase 1 for Operator A. Midfield terminal is Phase 2 while the last part is Phase 3.
Phase 2 and 3, theoretically, though not ideal, can be operated by different operators since Phase 3 can be accessible by road separately from Phase 1.
