Dive Luggage and Carry on Bags: The August issue of Undercurrent details airline restrictions coming in September that not only limit the weight of each bag a passenger checks, but also the total luggage weight. If you don't abide by the rules you'll be charged a fee. Too much weight and you'll be required to ship the bag (which means you'll miss your flight while you track down an airport shipper - and it will cost a fortune). The latest baggage restrictions, imposed August 11, should not affect divers, however, keep in mind that each country establishes its own rules. In many smaller countries, officious immigration and customs personnel can be haughty and arbitrary. They often order travelers to remove strobes, battery packs, even computers from carry on luggage. Be prepared. For information on US restrictions visit http://www.tsa.gov.
