Airline Regulations eased or new ones added?

          This CNN article describes major airline reactions to the latest change to Airline regulations  electronic devices are now allowed during all parts of a flight.  The only hitch is that you have to get each aircraft approved by the FAA to be able to do this.  US Air and Southwest will be among the first to  receive approval (They are also among the largest airlines in the US).  Spirit Airlines (a smaller airline) on the other hand did not give a time table of when their aircraft will be approved.
          While this may seem like deregulation, this could be another example of rent seeking by the large players in the airline industry.  The cost of filing the additional paperwork to get the luxury of allowing electronics at all times on aircraft is more easily covered by the incumbents in the industry with larger market shares and deeper pockets.  At first glance, this appears to benefit passengers, but the new regulations could concentrate the market even further raising both profits for larger airlines and prices for their passengers.
