I purchased 3 tickets to Tokyo. When the airline changes the plan, they didn't know. After I found it, I spent a lot of time to contact them and then they asked Japan airline to change my plan. However, one of the ticket was voided. When I tried to call them, it was very difficult to find their telephone number. After finding their number, all is answer machine voice. After I used my wit to connect the person, I waited and waited but not voice coming out at all. I also booked 1 ticket with another travel agency, UnderPricer. They noticed and changed my plan as soon as the Japan Airline changed. Don't have so much trouble as the JustFly has.
