Well it might do, that's clearly the aim.
But only if sufficient passengers who would otherwise take a carry-on opt instead for the cheaper fare.
If, on the other hand, the fare only attracts those who would be travelling light anyway, then they will have to queue up behind the bin-stuffers and boarding could well end up taking longer than before.
