During a long layover, travelers have several secure options for luggage storage. Most major international airports offer on-site left luggage counters or automated lockers, often located in the arrivals hall or near ground transportation; these usually charge a daily fee ranging from $10 to $20. For more flexibility, third-party services like Bounce, LuggageHero, or Stasher allow you to book storage at nearby hotels, shops, or cafes via a mobile app, which is often cheaper and more convenient if you plan to explore the city center. Some high-end airport lounges also provide secure storage areas for their guests. Additionally, if you are staying at an airport hotel for a few hours of rest, they will almost always hold your bags for free. It is important to remember that if you are on a "self-transfer" (separate tickets), you must collect your bags anyway, whereas on a single ticket, your bags are usually checked through, allowing you to leave the airport with only your carry-on for a "luggage-free" city excursion.
