My story is similar to
@ja1's. Since returning from Japan in Feb 2020, the only flight I have taken is the 747 farewell. All my leisure trips and visits to family have vanished. All business development trips, cancelled for the foreseeable future. No conferences running to either attend or, more commonly for me, present at, so no travel there.
In terms of work, I usually deliver face to face training for government and large corporate clients. This typically involved at least 1 trip a month to somewhere in Australia other than my home in ACT. None of that has happened in 2020 and I have no forward bookings for 2021 either - I usually book out 6 months in advance, so by now would have expected to be taking bookings for Feb-Apr 2021. For me it is not so much zoom meetings, but rather another pretty clear reason - no one can keep up with the border closures. And no one wants to pay for/absorb the cost of quarantines. And no one is ever sure whether the border closures/quarantines are long or short term. So my clients in Adelaide, for example, have expressly said that they will not be booking for the foreseeable future. This certainly reduces my use of flights. I do think that once the internal borders settle down on a predictable more permanent basis, my face to face training will resume, and so will my flight use. However, who knows when that will be....
