One of the most popular Phil Collins shows of 2019 was Friday October 4th at KeyBank Center. Interest for that show was at its highest when ticket sales began. The interest resulted in high ticket prices that dropped as the show neared.
Across all Phil Collins shows in 2019, interest was strongest right when the shows were announced and tickets went on sale. Meanwhile, ticket prices typically fell about 25 - 30% from the date a show was announced until the days leading up to the show.
