I had checked flight prices on multiple sites in the weeks leading up to my final purchase. On the day I was finally ready to book, I checked Kayak, Expedia, American Airlines, British Airways, Delta and a few others. The flights I ultimately booked on JustFly didn't show up on many of the other sites - certainly not for the price I paid. I didn't rate them a 5, however, because the first time I tried to pay for my flights I couldn't because the country code for my telephone was blank and it wouldn't let me select anything or move forward without it. I ultimately had to abort that attempt and try going through the whole process again. The second time through it had the country code filled in already. I ended up with the same flights for the same price, and it didn't take me that long to redo the process, so ultimately it was fine. I haven't actually taken the flights yet, though. If any problems arise at that point, I will update this review.
