Answer 1

The best solution for this problem is not using the same grid for flights and flight details. You could nest your details in the cell you want it to sort with.

Ofcourse you could also just turn off sorting. Or if you really want to hack it you override the sort event with some custom sorting. But that is very prone to bugs.
