LLL - Lost Luggage Lifesaver
On any plane, bus or train trip when you are separated from your main luggage (e.g. suitcases) always ensure you carry a day pack with enough things to survive on for a week.....3-4 changes of underwear & socks, towel, soap and shampoo & deoderant which don't trigger security and as many footstuffs and healthy snacks you can fit. Then you are not devastasted and still able to enjoy your holiday for 2-3 days until either your luggage (or insurance cheque) arrives!!
