......................the pricing of airline tickets?
Friend Bilbo is on the case. His easy explanation is here. Wee excerpt here:
"Then there are the surcharges, the ma'am charges, charges for carry-ons, charges for luggage, charges for more desirable seats, charges for preferential boarding, etc, etc. And no matter what you pay, there is no one else on board the airplane who is paying the same amount you did."
