Midwest and Frontier became wholly owned subsidiaries of Republic Airways, but each continued to operate under its own branding.

Deliveries are scheduled to begin in 2016, and the new aircraft, part of the ongoing fleet renewal program that will replace older aircraft with newer and more fuel-efficient ones, will allow Frontier to reduce its operating and fuel costs and grow in new markets.
