Thanks for reaching out to us on SiteJabber. You can find information on our cancellation policy here http://www.justfly.com/help/faq/I-have-to-cancel-my-flight
We always recommend that you confirm your reservation directly with the airline 48-72 hours prior to departure, regardless of where you book. This is to ensure that your flight is scheduled to take off as usual. If you have any questions or concerns, send us a private message and we'll be happy to help!
