In the quantities we're talking about - it's unlikely. If we're going to take a small amount of alcohol seriously, then lets also consider the effects of re-breathing your own carbon dioxide due to a mask covered in moisture from your own breath. As carbon dioxide pollution increases, people's rational decision making capabilities also decrease. I would suggest people are agitated for a few reasons: 1. They are being forced to wear masks. There can be a whole list of legitimate reasons you may not want to wear one, including preference. 2. They are being put into close proximity with people that may or may not have COVID. They've been told for an entire year that there is this super killer virus and for the large majority of people, it's simply the flu. 3. People are generally worse off than they were a year ago. They have significantly less income, the flights cost more (due to COVID measures) and their money is now worth less due to inflation. To make matters worse, if you're an alcoholic, stressed or scared of flying, you can no longer have a small drink either. And that's not to mention that drinking a shot of spirit for example would actually have the effect of killing COVID in your throat.
