American Airlines passengers will have to wait a little longer before alcohol sales resume in the main cabin. That is because the company has decided to extend its suspension of in-flight alcohol service until Jan. 18, 2022. "We are doing all we can to help create a safe environment for our crew and customers onboard our aircraft," American said in an internal memo obtained Thursday. This is not the first time the carrier has pushed back the suspension's end date. Shortly after Southwest banned a passenger accused of attacking a flight attendant and knocking out two of her teeth, American announced it was extending the suspension of alcohol sales until Sept. 13. <br/>
