My last international trips were last year Jan + Feb --- ICN, PVG, NRT, and BCN. My last time thru US Customs resulted in a dreaded 'X" at the Global Entry kiosk, my passport being put in a lock box, and an hour+ with a nurse from the CDC who was quite sure I had to be a super spreader. Thankfully, no COVID.
I cannot wait for restart of business travel even if I have to sit in seat 42B for 15 hours.
