Frontier offered RT's from San Diego to Vegas for $38. No checked luggage. Only a personal carry on no larger than set dimensional guidelines. I bought two. My bag was 1/2" too large, but could still fit under my seat. I was rudely denied flight. They told me it costs $189 to check the two personal items each. I complained and asked for refund and was told, "Our airport staff is trained to determine if a bag qualifies as a personal item or has to be paid for as a carry on bag. I'm sorry to hear you don't agree with the policy, regrettably, we must inform you that your request to be refunded cannot be fulfilled as it states in our terms and conditions on the website."
How is this fair? It just isn't, it's a rip off. If my bag fits, it should ship.
