I had to travel a lot for my job, both domestically and internationally. In the early days if the boss said I need to go to "somewhere" I didn't ask why I just went. It was an adventure and it was back in the days of no security lines, few if any crowds, friendly flight crews, and smoking was allowed on planes. As time went on, it became a PIA. Crowds, no smoking, security lines, etc. The last few years of my working life, if the boss said I needed to fly somewhere, I'd ask why? If the reason wasn't good enough, I'd say no or send someone else. If the reason was good enough, I'd say only if I can go business or first class, which he always approved. Even that became intolerable and air travel is one (of many reasons) I retired early.
And it's not just the flight and getting through the airports. It's getting a rental car, checking in and out of hotels, packing and unpacking, filing expense reports, and all the associated BS.
Since retiring I have not been on a plane and I see no reason to ever fly again. I see no reason to pay good money to be treated like cattle. Already seen as much of the international world as I care to see. Been there and done that! Now it's drive or I won't go.
