As is being reported by multiple sources, airfreight rates are going up if you can find the capacity at all. This, mostly, is due to Apple and the launch of the iPad 3.
Amazing that one company and just one product can do this but when it is Apple anything is possible. My sources tell me this could continue for 3 - 12 weeks depending on sales. Given that sales are already being pushed out if you order on line (indicating they are already in a backorder situation) my guess and money is on the bigger number.
