Shady business practices. They offered seat selection which I ordered and was billed for. The airline doesn't offer this service (you select your seats oncheckin)and yet Flight Network billed me for it anyway. I got to the airport only to find out that I payed for something that doesnt even exist. Also, the markups on the luggage was more than double what the airline was charging. FN wouldnt refund the money for the seat selection even though the airline (Frontier) confirmed it's not an option until checkin. Don't be fooled by their pricing...it's cheaper to go straight to the airline or through another service.
