Of course it depends on the circumstances and my schedule, but I think I would generally not be willing to accept "price vouchers" at nearly any "price" in this case. Every part of flying is a fairly awful experience -- from getting to the airport, the long lines, checking bags, invasive security, waiting, delays, being packed next to other people, more delays, waiting over an hour for baggage claim sometimes, potential for lost baggage, getting out of the arrival airport, etc. If I've already endured half of this rigmarole and have already boarded, there's no way a "voucher" for any price is going to make me want to take a later flight and have to go through all of this again from the start -- and my compensation being a voucher to get to go through this whole process again at a later date for "free".
No thanks.
For all medium range trips, I much prefer driving or Amtrak. I will put up with the airlines for very long trips -- but even then, I hate the whole experience, and I only do this when necessary.
