Heavy items near the wheels
Often we’re so concerned with space and where things will fit in our cases that we don’t stop to think about other considerations. You’re going to have to lug this case around airports, into cabs, and to your hotel. You don’t want it to feel overbalanced or top-heavy.
The best way of making sure you’re not wobbling all over the travelator is to place all of the heaviest items in your luggage down by the wheels. That way, when you put the case upright, the weight will be well-distributed and you can run smoothly through the departure lounge toward the gate.
