Most people will likely prefer Scott's Cheap Flights over Dollar Flight Club. Scott's Cheap Flights has much more flexibility for members; you can choose more airports and see more deals with each level of membership than you can with each comparable membership level in Dollar Flight Club. However, if you're someone who likes to fly first class, the jump from Premium to Elite membership is a big leap in price. Unless you fly a lot, it may be more than you want to spend.
