Same problem. Had my daughter on a flight bos-EWR-sxm. Received zero notification. Just happened to see something on fb so I called (yes they had hers and my email). They only cancelled the EWR-sxm legs! But kept her going from Boston to Newark!!!! I’m supposed to receive full credit. Now have her on Delta and JB. It will be interesting. Because it’s the New Years holiday I just went ahead and booked. By the time this trip is over she may have been booked on every commercial airline out of Boston!!
