United Airlines has sent a memo to its flight crew members: enough with the duct tape.

After a handful of recent incidents that saw unruly passengers duct-taped to their seats, United told employees to use different tactics – including de-escalation or other in-flight safety tools.

The memo said “alternative measures such as tape should never be used”.

Last month, a man was taped to his seat aboard a Frontier Airlines flight after groping and fighting multiple flight attendants.
