In May of 2021, I flew to Kansas City, MO, to honor my mother upon her turning 101. Shortly afterwards, (in September) she died unexpectedly. I flew to my former home again nonstop. Because of a physical medical problem that I had at the time, I sat in the very first rows on Southwest and felt rather safe.
For Christmas I flew nonstop from Monterey, CA (my regional airport) to San Diego (first class) to be with the family of my first cousin. Only vaccinated family members were present. I was not apprehensive.
For right now I do NOT have an interest to travel because the Omicron variant is so pervasive. I want to travel to Washington, DC in May or June, but this is only a plan right now. I have not begun to make any definite plans.
If you can wait for a few more months or perhaps a year, that is what I would do. My traveling via plane or bus or train is NOT in my immediate interest, and have been fully vaccinated and boosted.
