pilot fish:Self imposed fines and "restictions" are very ineffective.You can see from the wide slack they have given themselves " -5 hours- covers their butt. People don't want a voucher for future travel on JetBlue when you have screwed up that badly, they want their money back so they can fly on another airline.
Only if you assume that there is no incentive for them to avoid having to honor them. But, in your view, airlines have no incentive to move passengers to their destinations efficiently. Once they have your fare, the goal is abuse?
Do you honestly believe that this sort of thing happens all the time? 11 hours, 5 hours, 3 hours, 2 hours on the plane? Seriously?
And, given the number of people who will voluntarily bump themselves from oversold flights in order to collect vouchers on the airlines that oversold the seats, I think, in practice, you might also find that your second assumption is equally skewed.
