Frontier typically offers flights a few times a week as a way to avoiding head to head competition with airlines like American.
The airline offers low fares on short-haul routes with extra charges for luggage in overhead bins and assigned seats. It also offers a bundle that for an additional charge allow a carry-on bag, checked bag, and full refunds.
Frontier has nearly 80 Airbus A320 Family aircraft with nearly 200 new planes on order.
The company has worked to improve customer service levels beyond those of ultra-low fare rival Spirit.
Consumer Reports had Frontier finishing ahead of Spirit, but below United and American.
Frontier is owned by Indigo Partners, a Phoenix-based investor in airlines that sold its interest in Spirit while buying control of Frontier.
