I used ChepoAir to purchase tickets on Alaaska. The agent told me the prices I had found earlier had gone up, later I checked and the had not gone up. He told me I needed to pay $15 per ticket in order to have our seats together. Alaska Air says I didn't. He did not tell me they charged $30 per ticket service fee! I know it's not the end of the world, but a large family on a tight budget, I over paid with ChepoAir by about $150. Chepo Air is not CHEAP, Just a RIP-off!
