Measures are already being taken:
American Airlines bans alcohol on flights to and from Washington after Capitol riot.
American Airlines said on Thursday that it had banned alcohol on flights to and from Washington at least through Thursday night and was taking other precautions to keep its employees and passengers safe after a pro-Trump mob stormed the Capitol on Wednesday.
The company said it had increased staffing at the area’s three main airports. United Airlines said it has also stepped up airport staffing and had moved crews out of hotels in downtown Washington earlier in the week. American, United and Delta Air Lines said they were in close contact with local and federal authorities.
Even before the attack on the Capitol, airline crews and passengers had reported encountering unruly passengers headed to Washington early on Wednesday. Flight attendant unions expressed concern after members reported having to confront passengers who were being disruptive, behaving aggressively or flouting mask requirements. Video and photos posted on social media showed pro-Trump passengers cheering, singing and yelling at other passengers.
It continues. Now as far as treating people as individuals goes, that's all good and fine, but when you have groups of people like this, all gathering together and rallying around a political issue, that steps it up a bit from just some lone traveler being a jerk. If groups of people are being jerks, as has been the case cited above, now you have to step things up a bit more.
That is entirely reasonable, and correct to do under those circumstances.
Mob mentality, resulted in yesterday's attack on the Nation's Capitol.
