Air freight


Temperature during air freight is in general not as well controlled as during land or sea freight.  The result can be increased product temperature and then decrease in product quality and product value.

In order to minimise the risk of undesirable thermal loads on the perishable freight the following is recommended:

  • Apply precooling before packaging.  Fish products packaged at -0.5 °C can take more temperature abuse than products at 4 °C when packaged
  • Use well insulated packaging solutions and pack as densely as possible, given the products requirements
  • Check product temperature before shipping the products
  • Ship products to the departing airport as late as possible, especially if refrigerated storage is unavailable there
  • Temperature controlled transport to the airport should be used
  • Protect the products from challenging climatic conditions such as rain and direct sun.  Thin polyethylene films protect against rain but not the sun
  • Select a direct flight to minimise the number of thermally hazardous interfaces in the chill chain
  • Make sure that all necessary documentation is sent beforehand to the collector of the cargo at the destination airport
  • Make sure that the freight is collected as soon as possible in a temperature controlled vehicle and no delays are in the transport to the client/market
  • When a new freight forwarder/airline is taking care of the air freight, the temperature control in the chill chain should be investigated in at least three separate shipments using  4 – 6 temperature loggers each time
