For an airline, the price of economy-class seats on any given flight may fluctuate over time. For example, the airline may try to fill economy-class seats by lowering the price as the day of the flight draws closer, or try to fill business-class seats first by raising prices on economy tickets. This is an example of:
a. market pricing.
b. price skimming
c. odd pricing
d. dynamic pricing.
e. seasonal discounts
