Not everything is dropping. Airlines added surcharges when fuel prices spiked and I haven’t heard they’ve been removed. They also eliminated “free” dinners and lunches (they were never really free) on long flights, jammed more seats into Coach, and reduced the number of carry-ons allowed.
That's just it --meals, carry-on's, seat width, all this stuff is paid for by customers whether they use 'em or not. Personally I prefer being given the choice on what I'm paying for, so when I fly I like having my ticket price set after I say how many bags I'm bringing.
