If by drive prices down you mean encourage enshittification where checked bags cost extra so every damn person brings two "carry ons" and every damn flight the crew has to beg for volunteers to check their bags so there's enough room for everybody to get seated without an incident into the seats they had to pay extra for because only the ones with an inch and a half more leg room were left and they cost extra along with extra to actually choose which seat you sit in instead of being seated randomly away from your traveling companions so you can pay extra for food while the flight crew pitches the airline's credit card to you so you can afford the personalized price for your next trip. Nah, they can rot.
