The US Transport Secretary Pete Buttigieg has urged passengers to respect mask mandates and plane crew, after an altercation left a flight attendant with concussion and missing teeth.
A passenger was given a permanent ban from Southwest airlines after an altercation on 23 May. Vyvianna Quinonez was accused of ignoring orders from staff before striking a member of the flight crew.
"As we've communicated previously, we do have a process to permanently restrict passengers from travelling on Southwest, and please know that the passenger involved in the most recent incident has been advised that she may no longer fly on Southwest Airlines," read an airline memo seen by USA Today.
The flight attendant lost two teeth and suffered other injuries to her face, according to AP reporting.
Quinonez, 28, is also facing a charge of "battery causing serious bodily injury" connected to the incident, according to the Port of San Diego Harbour Police Department.
