The "best" way depends on whether you value cost, convenience, or speed. If you want to avoid the airport hassle entirely, specialized luggage shipping services like Lugless or Luggage Forward are often considered the best. They provide door-to-door service, allowing you to bypass check-in lines and baggage carousels. If you are looking for the most budget-friendly option, using standard carriers like UPS or FedEx Ground can actually be cheaper than airline "overweight" fees, provided you book through a third-party consolidator. For international shipping, DHL is generally the most reliable due to their extensive global customs network. To ensure your suitcase arrives safely, you should always double-tag it (one tag inside, one outside), use a TSA-approved lock, and consider "shrink-wrapping" the suitcase or placing it inside a heavy-duty cardboard box to prevent the straps and wheels from getting snagged in the automated sorting belts used by shipping hubs.
