(Reuters) – Southwest Airlines (NYSE) Co. will resume alcohol sales this month on its flights after almost two years. The Texas-based airline said Thursday that it would be resuming alcohol sales on its flights, a pause the carrier extended last year because of an increase in passenger-caused flight disruptions.

To avoid passengers having to remove their masks whilst eating or drinking, most domestic U.S. Airlines had suspended all in-flight service on domestic flights during the COVID-19 Pandemic.

Southwest, the alcohol service provider, had stopped selling alcohol in March 2020 because of the pandemic.

On most flights over 176 miles (283.24 km), or more, the beverages will include wine, vodka and tequila. It also announced that it would add tonic water and other non-alcoholic beverages, such as apple juice, Coke Zeros, Dr. Peppers, hot tea, and cocoa.

Tony Roach (Vice President Customer Experience and Customer Relations), stated in a statement that customers have indicated a desire to try more beverages.

Southwest Airlines’ flight attendants are represented by the union. They said it was both unsafe and irresponsible.

Lyn Montgomery, the president of TWU Local 556 stated in a statement that she is offended by Southwest Airlines’ resumption alcohol sales.

We have made it clear to management that we believe that increasing sales while the Mask mandate is in force has the potential of increasing customer non-compliance as well as misconduct.

Southwest didn’t immediately reply to Reuters’ request for comment regarding the union statement.

Southwest extended the suspension of alcohol service last year after an assault by a passenger on a flight between Sacramento and San Diego.

U.S. airlines reported a record-breaking number of violent and disruptive incidents in 2021. The U.S. Federal Aviation Administration pledged a “zero tolerance” attitude towards passengers who are unruly.
