Mostly fly SEA-LAS and LAS-SNA on Frontier. The $20 per flight airfare is based upon all travel in the last year. This year I have flown 10 times on Frontier and have spent a total on airfare of $100. The taxes and fees were about $200. Average total rt to Vegas is only $60. This price is why I fly Frontier even though I am Alaska Airlines Elite. I fly Frontier to Vegas because it is less than a third the cost of Alaska. BTW as Frontier Elite I get free carry-on and big seat with priority boarding. Can't achieve that status on go wild pass.
