Hmmm, could be the other way around. Netjets is born from the idea that a company jet is unnecessary excess. Even for a charter, getting six members of staff to a location and back in a day in a biz jet/tp is probably not that much more in cost than than mileage, parking, loco, hotel, meals, etc...probably more productive/efficient too.
As short haul travel is relatively cheap compared to the options and possibly considered more a utility than a luxury by many these days, I don't see the doom and gloom just yet. No doubt things will slow, but I'm not sure about a significant reversal.
