One of America's biggest airlines is adding a new perk for wine lovers.

On April 7, Southwest Airlines announced it was beginning a new program called "Sip and Ship," allowing its customers to check one case of wine at no cost.

The deal applies to select West Coast locations and was announced alongside Southwest's launch of service in Santa Rosa, California, in the heart of Sonoma wine country.

Starting April 24, the perk allows passengers age 21 and older to check up to 12 bottles in one properly packaged wine case — subject to standard baggage limits and route restrictions, with no liability for damage.

Wine cases "should be placed in a standard wine shipping box or wine suitcase that meets checked bag requirements," the company noted.

The program is only offered to customers flying to and from certain West Coast locations, including Santa Rosa, according to the airline.

"Being able to bring a case of wine home without added cost removes a common friction point and makes the trip feel more rewarding," said West.

"It also signals a broader shift where airlines are looking beyond just the seat and focusing on enhancing the overall travel experience."
