Why are there different fares offered to passengers on the same flight?
Airline fares vary constantly. On the same plane, you are almost guaranteed to have at least half a dozen different fares. Discounted fare levels vary depending on the advance purchase of the fare, the minimum stay requirement and availability level. The lowest airfare on the plane will have the least amount of seats available and the highest airfare will have the most. Review our Lowest Fare Tips section; it may help you find the lowest fare.
