I just booked a flight entering departure and return dates. However, JustFly's system substituted alternate dates a day earlier for both departure and return. THis was not made obvious nor did they offer a comparison or a chance to confirm the date change. As soon as I called JustFly to cancel the incorrect booking due to the surprise date change, they slapped me with a $75 fee and a $15.95 seat assignment fee. When I called them to resolve this, they refuse to refund the fees. These are sneaky and cheating business practices. Beware and stay away from a corrupt company!
