My understanding is that the next flight was something like the following afternoon. Business travelers are basically not going to voluntarily take a later flight at all. With respect to vouchers, most people don't travel all that much so a 1 yr. voucher isn't worth much. But offer cash (or a voucher at 2x) and you'll get people at some point.

This. As a business traveler, I don't know how I would justify this to my finance department and/or management. It would take too much effort to justify the change in travel plans for a shitty voucher that I'd probably never be able to redeem.
