Nobody in business is budgeting for air travel, at all. We used to put significant amounts of budget provision into project budgets for air travel, the last few projects have zero provision for air travel (or any travel for that matter) for at least the next 6 months. Business has adapted and I suspect it won't go back to air travel for a long time if ever.
So, you may want people to believe air travel is 'safe', but almost nobody believes that this is the case, and times have changed . . .
