The regulation says that airlines must offer at least this amount before they start involuntarily removing people. Airlines are free to offer more, they just can't stop at a lower amount.
So back to the point, how is it correct that regulations got us into this mess of ~$1300 capping?
Without this regulation, would airlines be able to bump people involuntarily with no compensation at all? If so, then the regulation is a clear improvement.
Or would airlines be unable to bump people involuntarily without this regulation, being required to offer potentially unlimited compensation? If this was the case, then the regulation gets a huge share of the blame for this.
I'd think it would me more like the second one here, but I could be wrong.
