I'd often be perfectly happy to take earlier or later flights on the same day, and potentially even change routing (OAK vs. SFO, or even something crazier like MIA vs. FLL). Wouldn't even necessarily need to offer cash; frequent flyer miles or upgrade to C or F or even lounge access while waiting would be fine. Rare other times, I'd probably want >$5-10k to change my flight (missing a speaking slot at a conference or a customer meeting or something when booked close). Being able to surface customer preferences like this seems valuable. I've had Alaska/Virgin call to offer compensation to change (or cancel) flights before, either due to overbooking or downgauging, and I've had international flights change and offer free rebook/cancel as a result, but nothing has really been technically efficient or easy to use yet.
