If they get rid of economy and make it all economy-plus are you willing to pay for it? Everything is market-driven, if everybody objected to economy and didn't pay to fly it, things would change.

Most aren't willing to pay more and prefer to, or can only, pay the lowest cost possible. Most people seem perfectly content in economy, so I think your view if it is the exception.

I hate flying in economy, so I pay not to.
