LBP sounds nice on the surface, but it reduces the incentive for the company to bring the 100 seat flying in house. When you start factoring in the flight crew portion of CASM on the A220 vs the B765, the math doesn't work out well at the same hourly rate. LBP works well at UPS due to a similarly sized fleet. Banding like FedEX or UAL could work well at Delta, because it addresses the broad range of the fleet.
