Corporate air travel is what keeps US airlines in business. I should know; I'm self-employed but work as a consultant on mostly-corporate events. I fly a lot most years.
Corporations keep track of every second their employees are working and make decisions on the value of every second, as they reckon it. That's how they justify having private jets for their top Executives. That $10,000,000/yr. Exec makes about $19/minute, if you consider them to be on the clock every second of every day. If you get a few such Execs going to the same place, and you can save them a few hours by having a private jet, in corporate finance terms you've saved the company money.
Corporate America isn't going to put up with having all their road-warriors on the clock for more hours per day because of President Trump's ineptly having painted himself into the Mother of All Corners. Corporate America will come down on GOP Senators and get a solution that meets their needs, just as the home mortgage industry got the IRS employees who verify incomes paid through incoming tax revenues so the home mortgage business didn't come to a halt.
