Yes, bassinet issue again... .
Having done lots of WTP flights I, more often than not, select 15J on a 777 on the basis that I can nab 15K at T-72: 15K being a bassinet. However, I've noticed on several recent bookings that 15K has been assigned before T-72 and behold, no infant/parent - only a fully grown human. It would seem that there must be a way of assigning/overriding the T-72 rule... .
