our partnership with Midwest Airlines

Frontier and Midwest are now part of the same Republic Airways Holdings family, and we are aligning with Midwest Airlines to bring added benefits to you, like the ability to book Midwest flights through FrontierAirlines.com and earn EarlyReturns miles on all Midwest flights. Though we hope to make this process as invisible to you as possible, you can expect to see some policy changes (mostly for the better) and some ticket counter consolidation at the airport.

Be assured, that though our family ties are new, our common commitment to the highest-quality customer service is not. Regardless of which aircraft you board, you'll find a safe, reliable, comfortable flight experience.

We've expanded our codeshare agreement with Midwest Airlines! Now you can purchase a ticket from Frontier Airlines for flights on the entire Midwest domestic network. You'll enjoy service to several new destinations - view our route map for a complete list of cities.

how it works

• You'll book a Frontier flight and receive a Frontier electronic ticket and one or more of your flight segments may be operated by Midwest Airlines or Midwest Connect.
• Choose to earn either Frontier EarlyReturns miles or Midwest Miles by entering your frequent flyer number at the time of booking.
• When your travel day arrives, check in with the airline operating your first flight segment* (identified on your ticket and in your reservation).
• When you check in, you'll get boarding passes for all flight segments to get you to your destination.
• If you have a connection in any city, there's no need to re-check your bags. Your baggage will be seamlessly transferred between flights.
