Next please ! Hello sir , may I see your passport please ?   Yes , here you go .   Will you be checking any bags today .   Yes , I ’ d like to check three pieces .   I ’ m sorry , sir . Airline policy allows only two pieces of checked luggage , at twenty kilograms each , plus one piece of carry-on luggage . I will have to charge you extra for the additional suitcase .   What ? Why ! I am taking an intercontinental flight ! I ’ m flying sixteen thousand CMS ! How am I supposed to only take two , twenty kilo bags ? That ’ s absurd !   I am sorry , sir , there ’ s nothing I can do . You cannot board the flight with that large bag either.Carry - on bags must fit in the over-head compartment or under your seat . That bag is clearly too big .
