It sounds as though airlines are now going to start charging more aggressively for baggage (Jetstar already do), cutting back on food and other items to save weight on flights - American Airlines apparently have cut the no. of peanuts and pretzels in their on board packages with drinks and have saved quite a bit on fuel - sounds odd to me?
The next thing will be that we, the passengers, pay according to our weight - the more you weight the more you pay!
