That makes me laugh too - you usually see it on Airport and programs of that ilk on the telly.
Baggage allowance: 20Kg.
You have 70Kg of luggage sir - we'll let you have 45Kg for free but you must pay for the rest.
And then said passenger has a blue fit about the excess baggage charge.
You should try flying to Cyprus - the Cypriot women get on with:
1 bag of duty free
1 bag containing magazines and books
1 handbag
1 make-up (overnight) bag
1 wheel-on trolley bag
Then they kick up because the gate attendant will only allow them 1 or 2 pieces.
Why can't people read the conditions of travel and understand that if they are enforced, it's their lookout.
