While we are unable to hold baggage for longer periods of time, many airports have storage lockers for rent. When checking luggage, allow sufficient time for it to be placed on your flight. Baggage checked less than 20 minutes before scheduled departure at curbside or at the ticket counter will be tagged with a Late Check-In Tag. Although every effort will be made to get late checked baggage on your flight, in the event your baggage does not arrive with you at your destination, Southwest will not assume delivery charges to get your baggage to you. When you've checked your luggage, make sure you receive a separate claim check for each piece of baggage you've checked.
All carryon luggage is subject to inspection at the security checkpoint.
It could be required that gifts be unwrapped for inspection, so it's best to wait to wrap them until you've reached your destination. Never pack anything considered a hazardous material. Seemingly harmless materials can be dangerous onboard an aircraft. Variations in temperature and pressure can cause such goods to leak or ignite. If traveling with an electric wheelchair, you must check in for your flight at least one hour prior to departure to allow for disassembly, when necessary, and proper packaging of batteries.
