I've booked with several online travel agents before and there were certain things I never really liked about them.
However, when I had to travel to Victoria, BC for the summer, I had no choice but to book with another agent online. I tried JustFly, although I was a bit skeptical at first. Well, I was quite surprised at how easy it was to complete my booking.
Throughout my trip, I had no problems. When I was about to head back to Virginia, I called them just to make sure I won't get into trouble at the airport. Their call center agent was polite and assured me that everything was in order.
I was able to return to Virginia on my scheduled flight. It was amazing!
