something to declare

True or false?

If you have checked in luggage, you can dawdle as long as you like in the duty-free shop because the aircraft will have to wait for you.

False. International aviation rules insist that travellers must accompany their luggage, and aircraft captains are not permitted to depart until all passengers with checked-in bags are on board. But computerised baggage systems are becoming more sophisticated, making it easier for airlines to off-load the luggage of tardy passengers. This summer, the Dubai-based carrier Emirates has instituted a rule saying that all passengers must be at the boarding gate at least 10 minutes before departure. Arrive any later, and staff will use the Baggage Reconciliation System to remove your luggage from the aircraft hold.
