For the few dollars you save, it just isn't worth using this site. I did by mistake and didn't notice until I saw that even using my airline card, the checked baggage was not free, as the airline would have been. So I rebooked through the airline itself, and then when I went to cancel, I was put on "hold" for 10 minutes while the agent (Andy) had to check it out before he could finalize my cancellation. He had an accent and was difficult to understand. He kept having excuses for keep me on hold. Said he'd send an email and I could cancel, but finally did. He said it would take 7-10 days to get to the bank. I finally received the email he sent, and then the next morning had another (very obscure) email with a "required" response of "I agree" to the questions "Do you want to cancel this reservation?" The name "Wizfair" only appeared in small print on the bottom of that email Would have been easy to miss, then I would have missed my 24 our refundable period. The entire cancellation process took over 15 minutes by phone. No email cancellation options exist.
I believe this is a fraudulent site, because they make it very difficult to cancel any reservations within the 24hour refund period. Avoid at all costs!
