There is an additional cost for that seating especially when the airline has already sold seats and there's no two seats placed together. Most of this is a convenience fee if you know where you want to sit it's worth it to you to pay a little bit extra. So for you to say there's no additional cost is not true especially when the requirement is you must require that the person can cancel or rebook to other flights if those two specific seats you want aren't available. There is definitely a cost to the implementation of this plan. It is literally asking other customers to pay for one person's convenience.
