and pax would soon learn that schlepping a heavy bag around might not be such a good idea.
I have said this before on here, an effective way to make us pax reduce the weight of baggage hauled around would be to weigh passengers and thier luggage at check in. Make it attactive by rebating "unused" allowance as frequent flyer miles - or carbon tax credits!
I'd also like to see have duty free ordering in the terminal with delivery at destination - which gives you something to collect while you wait for your luggage to show up!
