You can also earn and redeem EarlyReturns® miles on all Midwest Airlines flights.

Earning: Be sure to enter your EarlyReturns® number into your reservation at the time of booking with Frontier or Midwest Airlines. The miles you earn when you fly on Midwest Airlines will also count towards your EarlyReturns® tier status.
