Just don't fly justfly.com. My wife and I used justfly.com to book a round trip from Newark to the Dominican Republic. We picked flights with times and dates to fit our work schedules and available time off. We specifically dud not check the flexible dates box. We double checked the times and dates, entered the credit card info and bought the tickets. Next morning, i checked the confirmation email from justfly.com and saw that they reserved us on different flights than we had selected. The justfly website does not have a phone number. We called the airline (United), were told the best they could do was refund our airfare minus the justfly "travel agent" fee of $125. They gave us a customer service number for justfly.com. We called and they claimed to be exempt from FAA regulations requiring airlines to refund without charge within 24 hours on reservations made more than a week in advance. They would not change our tickets to the dates we had selected, and they would not give us a refund without deducting a $125 fee. With some inconvenience and the cost of a night at an airport hotel, we were able to make it work, just barely. Because of the changed dates, my wife had to take a connecting flight home without me. She made the mistake of using justfly.com again, reserving on an evening flight 4 hours after our scheduled landing. Sure enough, the flight they gave her was different, leaving Newark before our first flight left the DR. Another csll to justfly.com and the same stonewalling. $77 for a cheap fare utterly wasted.
