The configuration on this aircraft is identical to the A319 in the Frontier fleet but has additional capacity.
This aircraft features Frontier's Stretch seating which are the first four rows of the cabin. These rows provide an extra 5 inches of legroom and may be selected at time of purchase or at check-in. These seats are free with the Classic Plus fare; $5 USD per segment for Classic fares; and $15 USD for Economy fares. Stretch seating is increased legroom but remains an Economy class product.
It has also been reported that none of the seats on this aircraft recline.
