The cargo business may be a volatile one but it is giving carriers like JetBlue food for thought.

Four years back the carrier terminated its cargo business. The official line was that the service was not profitable enough and that the airline's forward strategy lay in another direction. That philosophy seems about to change, though, since this week JetBlue has announced that it is considering re-entering the freight arena.

The airline has said that it has plans to be partnering with Aeronex Cargo to resume its cargo service, albeit on selected routes. This latter company is expected to set up the infrastructure necessary for JetBlue to progress the idea. It is understood that Fort Lauderdale will become the first beneficiary; further ahead, the carrier anticipates including routes to Boston, JFK and Los Angeles.
