One cannot book a package with air, hotel, and car on southwest.com. You can book air and car, then buy a hotel in a separate transaction, but no one would refer to that as a package. Even then, you are not paying for the car up front so vouchers cannot be used and the hotel booking will also not accept vouchers.

No, you cannot use a Southwest LUV Voucher to book a hotel. These vouchers are strictly designated for the "base fare" of a Southwest Airlines flight and cannot even be used for taxes, government fees, or optional travel charges like EarlyBird Check-In. In 2026, the only exception is if you are booking a bundled "Getaways by Southwest" (formerly Southwest Vacations) package, where you can occasionally apply specific "Vacation Travel Credits," but the standard LUV Voucher given for flight delays or customer service issues remains airline-only. If you have a LUV Voucher, the best peer-to-peer "hack" is to use it for your flight and save your actual cash for the hotel booking. Always remember that LUV Vouchers have a strict expiration date (usually 12 months from issuance) and must be redeemed and the travel completed before that date, making them a "use it or lose it" asset specifically for the skies rather than for ground accommodations.
