HWH-ALD: PQ, HWH-CSTM: GEN, ALD-CSTM: RL:-:HWH-CSTM AVL dont imply HWH-ALD been AVL..ALD-CSTM if in WL, will remain in same WL, even if CNF/WL HWH-ALD get booked!!
CNF PQ for HWH-ALD will lead no extra berth for ALD-CSTM, as its not PQ, bit will decrease overall PQ by 1 count!! Although, during charting, berth, if vacant, will be released to clear lowest PQWL, irrespective of any leg in between ALD-CSTM, say 4 station "A-B" & after "B", next lowest PQWL be cleared (thats multiplexing)!!
If ALD-MMR have X berth assigned as RL, it remain...
more... intact till booking opening day...If MKP shares same RL & ALD-MKP booking too have same RL assigned, then if 1 berth been booked for MKP-MMR will lead ALD/MKP-MMR AVL as "X-1, while ALD-MKP will remain AVL as "X"!!
