Not as soon as you think. Frontier is operating this way (not releasing schedules regularly) because they have no idea what their schedule will look like yet... They are experiencing a shortage of aircraft - some are coming out of service to get repainted in the new livery, all are having the DirecTV removed and they are also getting a few more rows of seating added. New planes are on the way - there's an order for the new Neo's - but won't come online till later. Plus with all the new markets they're unsure where to focus. It's an exciting time for Frontier but a situation that means it's going to be awhile before you can book deeper into March.
