I remember a time when low cost airlines meant just that - low cost. For unbelievably low prices, one could jet set off to the Greek isles from London for the weekend, or hop from Kuala Lumpur to Cambodia to visit Angkor Watt. Not any more. Seems like all the low cost airlines are raising their fees, and the latest is Spirit’s attempt to charge $100 for carry on bags.

Surely what matters most to the airline is how much weight is on the plane. When will the day come when airlines will start charging passengers for total weight, including body weight and all luggage?
