It is a policy of Ticketmaster and many of our venues that single seats can’t be left when purchasing online. This is done to ensure fairness to the venue and other buyers and to prevent a situation where a venue may be scattered with empty single seats - otherwise other patrons may be forced to sit on their own to attend the event.
If your desired seats are not available due to this, we recommend using our ‘best available’ function on our website's booking pages. This function will provide you with the best available seats within your preference categories.
Alternatively, if there are no other seats that you'd like for your show, we'd suggest checking the availability for other dates if it's on for more than one night.
