Airline DeregulationThe Civil Aeronautics Board (CAB) controlled all airline pricing, routes, and scheduling prior to 1978 deregulation. Influx of new low cost carriers have entered the market. Fares have decreased across the board for air travelers.Productivity has increased substantially.

Point to Point NetworkAirlines fly passengers from point A to point B with no stops in between (direct flight). Better utilization of aircraft and crews. Minimize travel timeNo need to disembark and transfer to another plane.No need to rely on other flights being on time at a hub airport. The network will not be as affected by weather or delays.

Disadvantages of the Point to Point NetworkMany cities may not operate on a point to point network. Smaller cities may not operate on these point to point networks because of demand. Higher fares. You pay for convenience.

Hub and Spoke Network Many airlines operate centralized hub airports.Typically larger in size and located in larger cities with the ability to handle hundreds of daily flights. Equation of n-1 routes. Network of 10 destinations requires 9 routes. Large hubs provide travelers with hundreds of flight options and locations to travel to. Hubs fly to smaller airports that point to point networks may avoid.

Disadvantages of the Hub and Spoke NetworkCongestion at the hub airport.Airline runs a tight schedule with as many incoming and outgoing flights as possible. This can lead to overcrowding at the airport. Passenger inconvenience.Passengers must disembark and connect to a second flight to reach their final destination. Connecting flights may be hindered by delays and loss of personal belongings. Weather and general delays can impact the whole system.

Airplane Manufacturers InputManufacturers seem to have picked sides in the argument between the two networksAirbus, with the A380 has gambled that airlines will fly smaller aircraft into its hubs, and then transfer passengers to larger aircraft.Boeing, with its new 787 Dreamliner argues that passengers demand more point to point flights on smaller aircraft with greater availability.

ConclusionDeregulation occurred in 1978.Allowed for greater competition in the industry as well as cheaper fares, improved scheduling, and greater choices in destinations. Point to Point NetworksAirlines fly from point A to point B.Simple network and great for passengers.Not the most efficient network.

ConclusionHub and Spoke Networks.Airlines fly passengers from smaller airports into larger hub airports to transfer flights. Airline can operate fewer flights to reach the same destinations as a point to point network. Saves airline money in the long run.
