It feels likes this is the culmination of all the little changes that have been happening over the past several months. It's the final F.U to airport ticket buyers since now they're incentivized to pay the CIC fee in order to earn more miles. These changes will cut my frontier flying by about 50%. Mileage runs to at least 3 cities of my usual cities won't be worth it anymore and I will be driving there instead and save money/hassle.
