Dynamic selector answers

Background

On a step, we have two selectors. "Travellers outside Wingly" depends on "Offered to Wingly". It works that you have N number of seats and you can share them or select that some seats will be taken. And you do not need to use all the seats even.
The problem that I run into is that most of the users will select all seats to share with Wingly. As it is convenient for the user I want to even preselect this option. But the dropdown is that then the second selector emphasized text(Travellers outside Wingly) will have no options to select which makes it counter-intuitive...

Question

Is there a better way to display the connection between fields "Offered to Wingly" and "Travellers outside Wingly"?
