My 81 year old mom wanted to book a flight on Frontier. These guys had an ad acting like they were Frontier. Mom bought a ticket for the same price she could have had on Frontier but there was also a $40 add on fee. She tried to change the date later that day but was told there was a no refund policy. The booking process was complicated - you have to respond to an email confirming you want the ticket.
These guys are rip-off artists working on deception and preying on the unwary. Avoid them. $140 down the drain for my mom.
