Not wanting to become the Dave Carroll of the classical music world, solo cellist Lynn Harrell purchases a second seat for his cello when they travel together. This should keep everyone happy. The airline sells an extra seat to a very quiet and compliant passenger, and Harrell racks up extra frequent flyer miles that he can put toward future travel for his cello. Delta isn’t happy, though: they’ve kicked him out of their frequent-flyer program and banned him from it forever. His crime? Accruing the frequent-flyer miles that the airline granted to his cello.
