On 10/21/2019 I flew from Leon to Sacramento. I had one carry on bag that weighed 8 kilos. I was told I had to check it and was charged $50 US because the flight was full. The flight was not full and many other people had carry ons. Today, Dec. 17th. I went to the web site to purchase to tickets from Leon to Sacramento and back. The total charges were $632.25. The site wouldn't confirm my purchase. When I called customer service they said the prices had gone up and they hadn't updated their website. I had to pay $704.06.
