I prefer a
contest, which is the opposite of a
protest.
-----------------
All kidding aside,
magexpect, there have been several protest movements, including
www.saveskymiles.com for Delta frequent flyers, and the “cockroaches” for USAirways.
While their goals have not solely protested the comfort of coach cabin seats, that item has been amongst the agenda.
Usually, frequent flyers are not as concerned about comfort in the coach cabin if they are able to secure upgrades more often than not. For some frequent flyers in this scenario, the relatively few times they have to fly in discomfort in the coach cabin is too minimal to worry about protesting.
Also, one trick implemented by many frequent flyers with flexible schedules is to find out which aircraft equipment is used as what hours of the day. This ensures a greater possibility of either an upgrade to the front cabin or more comfortable coach seats.
As mentioned earlier, other frequent flyers avoid certain airlines altogether.
I suppose more seats on an airplane means more revenue for the airlines, who need as much revenue as possible to survive these days, as mismanaged as the airlines may be. I further suppose that it is in our best interests for the airlines to survive.
Many frequent flyers do not have the time to protest even if they wanted to, I surmise.
I certainly do not have all of the answers, but perhaps these are some of the reasons that there is a mistakenly-perceived complacency amongst the responses in this thread,
magexpect.
