flying for the first time ever 2moro and want to get clear what luggage we're allowed to take. on my invoice it states that between our 4 passangers ( us 2 parents and our 2 little uns) we're allowed to take 2 bags with a combined weight not exceeding 64kg... our bags weigh no more than 20 kgs each (just weighed them) now I have 2 bags that I wish to carry on the plane as hand luggage... 1 is a rucksack and 1 is a small trolley case ( fits into the measurments required) what weight is the max allowed to carry on board? just checked and it says 20kg, is that right?? seems a bit much for hand luggage?? anything else you think I may need to know?? bit nervous can you tell???
