Beware. many hidden fees. The free 24-hour cancellation is subject to an "administrative fee". Seat selection costs extra though it does not state that explicitly on the site. You see the seat selection charge later on the bill. Changes fees are the worse. Justfly will charge a fee on top of what the airline charges. Their fee was higher than the airline's change fee. And mind you, all they do is book flights. They have little value added and bad business model. AVOID
