Carry on baggage, not Duty free bags
[QUOTE=Wiild;1355179]Never agree to pay excess after security, you are are allowed to buy as much taxfree as you regulations stipulate, they can't charge you for that. If they want to take your luggage due to overall weight they can do that but they can't charge you for it, if they claim it's too heavy say you bought 3kgs of candy, local goods or liquor.[/QUOTE]Was talking about carry on bag, nothing to do with duty free, which seems to be regarded as a separate and untouchable item / s. They sometimes check the carry on bag, not the plastic duty free bag which seems to be immune from checks. If you claim your carry on is full of duty free, all they need to do is ask you to open your carry on, and see if it is so. I am talking about straight forward carry on luggage, not duty free bag / s.
Most of time, overweight and oversized carry on bags, some as big as my check in bag, are allowed through as passengers are scarce to come by, competition allows, so they allow. But then sometimes an airline decides to control the carry on baggage, not duty free stuff, carry on. Thats when you can get caught with overweight baggage. Enternational has a light portable scale, so do I, which means you can avoid being caught with excess baggage, if you want to, or take the risk. Have you noticed in recent years, lots of folks panic to get on plane first, cause people are now taking on board bags as big as check-ins, especially backpacker passengers and the like. Hard to come by passengers and competition has forced some airlines to ignore the IATA rules. Budget airlines however are strict in respect of baggage. Consequently with non budget airlines, space in those overhead lockers has become premium, a real bun fight.
You can get caught, and when it does happen, you do get charged at excess baggage rates, and have the bag taken off you, and collected at other end as check-in bagge. I've seen it happen more than once.
