Delta Air Lines and other carriers are taking extra security measures ahead of the inauguration by banning the checking in of firearms on Washington DC flights.
Only members of law enforcement will be exempt from the ban.
The airline is tightening security at airports and on planes for flights to Washington DC.
"We’re all on high alert based on the events over the last couple of weeks in Washington,” Delta CEO Ed Bastian told CNBC.
"I don’t want to overreact. I think this is a moment hopefully in time with the outcry around the election results.”
American Airlines, United, Southwest and Alaska Airlines also later joined Delta in temporarily banning guns on DC routes.
American Airlines also said it would beef up security on the ground and won’t serve alcohol on flights.
American said it is moving flight crews on layovers from the usual downtown hotels to hotels closer to airports for safety reasons.
The FAA is getting tough with unruly passengers after ‘a disturbing increase in incidents where airline passengers have disrupted flights with threatening or violent behavior.’
"These incidents have stemmed both from passengers’ refusals to wear masks and from recent violence at the U.S. Capitol," the FAA said.
