It's been discussed on HN before [1], but it's worth mentioning in this thread that there's a YC-backed company – Volantio – working to solve this specific problem. Most airlines' position is that they have to oversell flights, otherwise planes will fly with empty seats unnecessarily. But from passengers' point of view, there aren't always enough people who'll voluntarily accept an offer to transfer to a different fl…
This is blatantly false. I fly all the time and I see this happen about every other time at a neighboring gate. Gate agent announced flight is oversold, makes an offer. Several people volunteer. End of story.
You don’t hear about these events because they (used to) happen hundreds of times a day all over the US with no hassle.
Then the stupidity of United and the ignorant backlash of the public ruined it. Infrequent fliers associated overselling with the United incident and completely ignored the functioning 99.9% of cases that benefited all fliers overall.
Volantio’s product is ok, but it’s not a substitute to the problem overbooking was solving, nor is it better for passengers who were flexible with last minute changes (because the offers are worse since rebooks days in advance don’t solve the last minute flex fare changes).
Ugh, sorry about the rant but this whole oversale thing is a perfect example of the outrage culture damaging a mostly functional market due to sheer ignorance.
