Just because the legacies have been doing that for decades does not make it the best system. Posting a dummy schedule and place holding equipment just so you can potentially sell a seat 330 days in advance makes little sense. The vast majority of seats for carriers which are focused on North America are sold within 2 months of the flight date.
