Unacceptable. Worst flight booking website I have ever used. Predatory cancellation fees even 10 minutes after booking even though I made it in error. I booked on this site because of a very low fare quote for our family’s trip to Jamaica. When I entered my credit card to finalize the booking a message appeared saying the cost had increased by $200 and whether I still wanted to proceed. I clicked yes. The booking completed and I found out that the increase was $200 per passenger and not the total. JustFly.com didn’t provide a final cost quote until the transaction had been completed. I was horrified and tried immediately to cancel. The website said to try later. After a few more attempts I got to a cancellation page that said my flight was fully refundable but I need to pay JustFly $225. I tried calling their customer service number and after navigating through many layers of phone menu I finally got through to a live person. She told me that I had to pay the amount. I complained and she reduced the charge to $25 per person to $75. As a matter of principle I said this was unacceptable and I needed to speak to her supervisor. After a long period on hold, a man introducing himself as Mr Leo (staff #3913) answered and said I had to pay ithe charge if I wanted to cancel the reservation. I asked to speak to his supervisor and he said that there was no one else that I could speak to. He essentially stonewalled me. I did a time check during that conversation and realized that this was all within one hour of accidentally making the booking. I asked for the USA address of JustFly.com and he said it was 403-175 Capital Boulevard, Rocky Hill CT 06067. As a matter of principle, I will be following up with them to express my disgust at such shoddy customer service and their predatory charges.
