Does anyone know if the Air Malta permitted weight of 10 kg applies to just the one main piece, or does it include the small personal item, i.e. main + personal must not exceed 10 kg? Also, the suitcase I have found is 8" deep, which is actually 20.32 cm. Air Malta states 20 cm. Will that extra .32 of a cm be a problem? 20 cms is 7.87" - just a wee bit smaller. I want to make sure it fits in their measuring cage.
