Final answer:
Price discrimination involves charging different prices based on willingness to pay. Offering cheaper airline fares for advanced reservations is not considered price discrimination.
Explanation:
Price discrimination occurs when consumers or groups are charged different prices for the same product or service, even if the cost of providing it is the same. An example of this would be charging different prices for the same product based on willingness to pay. In this context, airline fares being cheaper if reserved several weeks in advance would not be considered price discrimination as it's based on the timing of the purchase rather than the identity of the buyer.
