Ticketmaster recently adjusted its refund policy so that it only applied to events that were "canceled". Now, they've changed it.

Postponements and reschedulings were not refundable which left fans without their money nor with any clear idea as to when they would get to see the shows. If at all, since many fans had made special travel and work/family arrangements around those specific dates.

Following the tremendous backlash over this policy ... and the intervention of at least 2 members of Congress ... Ticketmaster has now amended it to include all shows; canceled, postponed, or rescheduled. Starting May 1st, fans have 30 days to decide if they want a refund, a credit for another show, or if they want to donate their ticket to a health care worker. (nj.com) A similar announcement came from Live Nation offering:

... loyal fans a variety of Concert Cash credits to put towards future ticket purchases. For cancelled shows fans can choose to receive up to 150% of their ticket value as Concert Cash, and for rescheduled shows they will receive Concert Cash once they attend the new date. - click2houston.com

Fans can also keep their tickets and wait to see if/when shows reschedule.
