Where is Aaliya???

Zain booked the tickets then he must have surely booked Aaliya, ghulam n shabana's tickets, too. So where are they??? Weren't they supposed to be with them in the aeroplane? But nothing lyk this was shown lyk suri being miffed with Zain for being with aaliya or anything

If we forget that then after they landed, where did they go?? chalo assuming they went to a hotel or at rehaan's or rizwaan's house, wasn't it a duty of zain to go drop aaliya n her family over there?? But he was shown entering BV along with his family.

So. WHERE IS AALIYA????😕
