In reality, you would more likely spend the evening in a waiting room at the airport customs office and perhaps be denied entry. But, I want the message to be clear that bringing goods into the country without proper customs paperwork is just not worth the risk, period. If you are bringing in more, it must be declared. The new limits are two carry-on items per person. Size limits are also in effect and vary slightly.
Implementation is now underway or complete.
It is expected that those who have not yet announced similar plans will do so soon. If your carry-on luggage exceeds the limits, you will be required to check them in. Briefcases, Laptop computers and tote bags count as one item. Exempted from the list are purses, assistance devices for handicapped people, child safety seats and outer garments. The new policies are being implemented to speed boarding and de-boarding, ease overcrowding of overhead bins and for safety reasons.
