The non-charter flights are as usual--you pay for extra luggage. The charter flight folks say one checked bag, 23kg/50.7lb limit. No more. No paying for extra luggage. They are concerned with weight. What's the difference between one 50lb bag and two 25lb bags? They'll put extra bags on a later flight, but that's too late to make it to the ship before departure. I suppose logic doesn't work with the check-in agents. Akin to the Soup Nazi: "No extra bags for you!" Grumble, grumble...
