I've been trying to figure out why airlines that don't overbook have such high IDB ratios compared to the other carriers.
If you overbook as part of the core revenue process, you probably have also refined the VDB process to minimize IDB (and cash outlay) - otherwise you erode the financial benefits of overbooking. I'd bet the carriers that don't overbook at all, or not as aggressively, aren't as good at getting volunteers to take vouchers instead of cash. They might swap equipment or something and start canceling tickets.
Just my speculation. I can't base this on any actual knowledge.
