Sounds impressive as well, but wrong. First off, there are two demand elasticities to consider. The first is the industry as you mention and the second is within the industry (carrier to carrier).luvn737s said:Demand elasticity is directly related to competition, not from other carriers but from other modes of transportation. In the US, there is no competition from other modes. Greyhound is not trying to lower it's fares to grab more of the transcon market.
The former (industry) decides whether or not a passenger is going to fly at all. You are grossly errant on your statement that there is no competition from other modes. First off, the industry demand (whether or not to fly) is seriously affected by competition from driving and alternatives to travel (teleconferencing or not to travel at all which is currently a popular decision among both families and businesses). Therefore, the industry fares dictate whether one flies or chooses an alternative. This is a fairly high elasticity of demand to consider and tells us that if ALL airlines would come along with a fare increase, that doesn't mean there will be more profits. The exodus of passengers may more than outweigh the higher yields.
The latter (carrier to carrier) has an even higher elasticity as there is so much competition now and passengers are extremely price sensitive that a carrier can lose chunks of market share in a single day of highly increased fares. Also, as has been mentioned earlier in this thread, different route structures and market strengths make it impossible for all carriers to increase fares at the same rate. Some, like NW, don't battle as much against WN b/c they have protection in MSP, etc. They can more readily increase fares than U who faces immense pressure from the LCCs in nearly all of its major markets.
So your statements about elasticity within the airline industry are full of simplified assumptions that are highly inaccurate. And the point is that U is not trying to create the deluge for itself by backing out of the "fare increases" by the legacies a few weeks ago. It is all a demand function that cannot be won with fare increases.
