Travel is a real pain with Covid. I remember having to get tested in Romania before my flight home. Scheduling the test and getting the results was difficult. I heard of false positives, especially for those who used excess numbers of cycles in running the test. Mine was negative. Even for the intra-Europe flight to Germany, I had to show the result, since my final destination was the US. It was a nightmare in Munich, however, as they had to check everyone's test for the TATL flight to the US. That delayed boarding for over an hour and we had to stand in a long line. The weird thing is, with this US imposed requirement, the most lax checking of test results was on arrival in the US. Two people stood in the jetway and randomly chose passengers to check their results. I doubt they looked at over 1 out of 20 people getting off the plane.
A genuine positive test would have been a headache and required making lots of arrangements, but even a false positive test would have done the same.
What I hated most on a long TATL trip was having to wear the masks constantly. At the time, my N95s all had exhaust ports so they would not allow those to be worn, so I had to fall back to the less effective KN95s I had available. Those attached around the ears instead of the back of the head like the N95s, so my ears were sore for days when I arrived in Romania. Masks on planes are silly since the air filtration systems on planes would filter out viruses much better than a mask would, and you take it off to eat and drink anyway. At that time, and probably still today, the only flights in or to Europe that had masks optional were domestic flights within Sweden.
Getting into Romania was also more time consuming. They required proof of vaccination, and people were divided into two lines getting off the plane. Those with the EU proof went to one line which moved quickly while everyone else was put in another line that moved very slow. After about 20 minutes fortunately the fast line had cleared and a couple of immigration guys came around asking what those of us in the long line had, and the US proof of vax cards were one of the few things they reconsidered and let us go to the fast line. From the number of people left in the slow line and the speed at which it was moving, It suspect it would have been two hours until they would have reached me if I had had to stay in that one. Once out of the airport, masks seemed to be, at least as a practical matter, optional, so I did what most people did and did not wear one. Besides at that time, the reports showed not many people testing positive there.

Rode around in a van for 7.5 hours with someone who tested positive the next day. That's been 9 days, still testing negative
