Work in tech; travel is 1 or 2 times a year for in-person team meetings (all Zoom all the time just doesn't quite cut it), for international flights over 6 hours PE is available even for us proles at the bottom of the org chart, and I make a point of negotiating to arrive about 2 days before the event so my body can catch up somewhat (usually about 15 hours of flying and 8/9 hours of time difference for me). Fortunately the concept of "spending a couple of hundred dollars on additional hotel nights so I can be productive when every one else arrives" is still understood within my chain of management as a sensible "investment".
