I was thinking the same thing. Instead of trying to "hide" a price hike in the already expensive fuel surcharge or ticket price which people will just swallow but otherwise ignore, you're going to have all these people who think they're being smart by bringing everything but the kitchen sink on board with them.
Watch, you're going to have more annoying situations like all the overhead bins getting full earlier and earlier before a big chunk of the passengers have even boarded. I feel for those passengers that board just in time and there's no overhead space, but now it's going to be people who are plenty early at the gate, but just because they sit towards the rear, their overhead bins will all be taken. It's bad enough that the airlines are cutting back on flights so that each plane flies as full as possible. Now it's cabin space that is going to be at a premium.
