Many airlines now charge a fee for checking-in hold baggage. Unfortunately there is no consistent charge for hold baggage: to find out the specific charges for your flight you must check with your airline.
Size and weight limits will also apply to hand baggage to be taken through security and onto the aircraft. The Airport permits hand luggage through the Airport security search point providing the dimensions of these items does not exceed a maximum length of 56cm, width of 45cm and depth of 25cm (including wheels, handles, side pockets etc). Please note that some carriers impose more restrictive dimensions than these so you should also check with your airline before travelling.
