The airlines need to look at the military to see how it can be done very cheaply.  The Hercules is capable of hauling 128 combat troops with all their gear.  This is no frills flying at its best.  Seats are nothing but tubing and webbing, all the luggage is carried on by the passengers, and loading and unloading is extremely quick by dropping down the ramp, no jetway required.  Bathrooms consist of P-tubes on the wall.  Paved runways are not required so any dirt strip can act as an airport therefore avoiding all the extra fees.  No inflight entertainment, no food or drink service, no fighting for overhead bins (there are none), and its really easy to load extra cargo if it pays better.  I've flown sitting on the floor with my back to a truck as a backrest.  It wasn't as bad as flying Air Canada.  If the fairs are low enough, this style of flying could really catch on.
