Live Nation recently started selling aisle seats at select shows with a surcharge that adds an additonal $5 to $30 to your ticket price . . . for those who are "looking to enjoy the convenience of easy access to refreshments, restrooms, and venue exits."
Even better: It's not ONLY the actual seat on the aisle . . . in some cases it's also the second, third and fourth seats into the row. Although for now, these price hikes must be approved by both the artist and the promoter.
