Fasten your seatbelts
The days of an economy ticket with a fixed price are coming to an end as airlines are charging everything from extra legroom to power outlets

Memorandum to all expenses managers and accounting departments: the days of the economy air ticket that comes with a fixed sticker price are rapidly coming to an end. The world's airlines are determined to make as much money as they can from each and every seat in the flying real estate of an aircraft.
Squeezing every penny airlines can from ordinary travellers is changing the definition of a standard economy seat.
Is it the one with more comfort and legroom, or that offers the flexibility of changing the date or flight?
Perhaps it is the economy class that gets you through security without having to wait in line for an hour, or the version with food and drink, or Wi-fi, or one that lets you sit next to your children, spouse, friends or business companions.
I have not met a grocery retailer who charges you extra if you want your milk cold or with a cap
PricewaterhouseCoopers has just produced a report in the United States that says airlines must view themselves in the same way as their customers do: "In today's competitive travel market, flyers are expecting airlines to behave more like retailers and less like a mode of transportation."
