Hmm, now that's interesting. The airline has concluded that by lowering the weight in the airplane, fuel consumption can be reduced.
In an effort to meet with the rising fuel prices,Air Canada came up with this solution - NO MORE LIFE-VESTS.
The passengers will - in all likelihood - have to use the inflatable pillows (which, as per boing boing - have to be bought in the Economy Class) - and use those as a floatation device, in the event of a water crash.
If things continue this way, I am sure Air Canada will manage to reduce fuel costs significantly. They really won't have much weight to carry, given that passengers would definitely start to opt for a more sensible airline.
