Select ancillaries (baggage, seats, meals) for a trip item
Add baggage, seat selections, or meals to a flight item before checkout. Use it after the trip has a flight item and travelers attached but before
book, for example when a user requests “two checked bags and a window seat for the outbound leg”. Selections use full-replacement semantics — include everything the user wants kept on the trip in a single call.
