Friends, before you fly international pls check the new baggage rules, adapted by your airline. Most Foreign airlines have started using the piece concept with the weight. Some airlines allow 64kgs or less for Biz class 2 pieces and Economy 1bag 23/32 kgs. For every additional bag you will have to pay extra even though you are within the permissible weight limits. Also note the airlines will not accept bags over 32kgs.
On a recent flight to Poland we had to pay for the extra piece even though we had less weight. This maybe new for gulf flights, as they were not implementing this rule before. Regards Edward Verdes
