I'm talking about the people who think United should offer cash instead of vouchers for voluntary bumping. There's a lot of reasons people WOULD want vouchers too. I'm surprised it got up to 800, anyway. People do snap up vouchers. It usually works.
It might often work, but it didn't on Sunday. They could have switched to cash offers and maybe someone would have accepted, but they didn't.
I wouldn't want a voucher. My vacation plans for this year are completely set (including air travel where needed.) My husband has no more vacation time, and I don't get paid when I don't work, so I don't really want to take additional time either. My vacation time is pretty much planned for next year, too. Airline tickets haven't been purchased yet (because the schedule isn't open yet), but United was not on my radar as being a good option for that trip. If I had vouchers, maybe I'd use them, but I wouldn't say "Hooray! United vouchers!" for that trip.
If we had the vouchers, maybe we'd go somewhere to use them... but it would be an unexpected trip that would incur expenses of its own (lodging, food, activities, boarding our dogs at home, and... as I mentioned no wages for me.) It would be kind of like getting a really good coupon for a store that doesn't have anything I really need. Sure, I am sure I could get something, but it would cost me money to do so. I might enjoy it once I had it, but it's certainly not something I need.
I probably would not consider voluntary bumping for a voucher. Chances that I'd be able to use it within a year are small, or would cause me more hassle than the enjoyment they'd provide. Cash might be a different story. If I could be flexible, for the right amount, I'd do it.
