JB cancelled our direct flight Saturday, 2/03 and return on Saturday, 3/03/18. When I checked our confirmation, we were automatically confirmed leaving Friday, 2/02 with a return on Friday, 3/02/18. I called to cancel stating that wasn't going to work and received a full refund to my credit card. I mentioned that JB had not notified us of the change by email, text or phone. The JB rep didn't know why. Luckily, I saw mention of this on a Facebook comment and investigated. Others may want to do the same.
