Plan your trip systematically, including packing in advance - do not leave arrangements to the last minute.
Add at least 30 minutes to your normal airport travel time.
Be sure to pack your own luggage, secure it properly (loose straps may catch in the conveyor belts), lock it, and if possible shrink wrap it and attach identification tags.
Do not place valuable items into checked baggage (such as cellphones, laptop computers or jewellery), and
Do not leave your luggage unattended - whether it is check-in or cabin luggage
