I've travelled 5 times internationally this year. Have to get tested going and coming. Pain in the ass but now just part of travel.
Funny thing: the country I have been visiting you could get in with a vax card or test for about two months. Then, even if you are vaxed you have to test as well.
Don't even get me started. Have been travelling a while (work). I sit at the front of the plane, carry-on only so I can get through customs, avoid the lines etc. No belts, watches, slip on shoes. All for the TSA bullshit.
BTW, not 1st Class, that doesn't really exist anymore. I pay for upgraded seats right behind 1st.
