I know a # of people who are holding off on booking international travel until they see what happens w/ the war. Of course the downside to that is that the airlines are already in a precarious mode financially; a large fall-off of travel will not help, and the zillion miles in our accounts could go by the wayside.
I agree that the flight fares will most likely go down, which means some cheap quick trips overseas. My only complaint is that, United at least, is upping the fare levels to upgrade, whether using miles or system-wide certificates so those cheap fares won't qualify. For those east coast-based, that's probably not as big a deal as it is for those of us west coast-based. 11 hours is a long time in coach.
I intend to keep on traveling, whether domestic or international (obviously avoiding any hot spots int'lly) & taking normal precautions.
