Traveling with your guitar requires careful preparation. Use a sturdy, hard-shell case to protect it from damage. Loosen the strings slightly to reduce tension, and pack additional padding around the neck and headstock. If possible, bring your guitar as a carry-on item to keep it with you in the cabin. Check with the airline about their musical instrument policy ahead of time. If you must check it, consider purchasing travel insurance to cover potential damage. Arrive at the airport early to ensure smooth handling, and always label your case with contact information.
