whatever you decide to take, make sure you have a change of clothes in each bag if you're taking more than one. That way you won't be completely forced to buy a whole new wardrobe when you get to New York and your luggage goes to Prague (although you may want to anyway )

If you are going on a very long trip and changing planes, pack a change of underwear in your hand luggage. It can be very uncomfortable arriving in Orlando at 11 pm after thirteen hours travelling, and discovering all your luggage is in Atlanta.

However, if your luggage doesn't turn up quickly, you have the opportunity to buy some new clothes and reclaim the expense from your travel insurance.

When returning from holiday, pack as much of the gifts and the like in your hand baggage.
That way when Innexperienced Atlantic choose to lose your hold baggage they won't lose the magical little wooden walking hedgehog toy that can only be found in Macau and offer you a complimentary biro to fill in your insurance claim with instead Grrr!
