Traveling long distances often means carrying more than just a carry-on. While many travelers rely on roller suitcases, a large number prefer backpacks because of their versatility, flexibility, and hands-free convenience.
However, when checking a backpack for a long-haul international flight, you need to pay special attention to security, packing efficiency, and airline restrictions. Unlike suitcases, backpacks are more vulnerable to damage, tampering, and mishandling.
