Nesting (of booking classes)

What?

Allows “lower” booking classes to cut into the capacity of higher ones, but not vice versa. This way, if there is demand for a higher fare but only inventory for a cheaper one, the booking class of the more expensive one will be automatically expanded.

Why?

Should be self-explanatory :sweat_smile:

When?

Obviously depends on Booking Classes and likely doesn’t make much sense without Fares.
