the overall cost of travel. The appropriate elasticity to use
will depend on the type of question being asked. What is
the price that is being changed (e.g. an individual airline
ticket price or prices within the market as a whole)? What

for an individual airline or demand for total air travel)?
Examining the traffic impact of a price increase on a given
route requires a different elasticity than when examining
the impact of an across-the-board price increase on all
routes in a country or region.
There often appears to be some confusion in policy
discussions about the sensitivity of airline passengers to
the price of travel. This has increased as the industry has
changed, with the Internet increasing price transparency,
deregulated markets and no frill carriers increasing
competition and corporate travel buyers becoming more
price sensitive. In particular, there is an apparent paradox
