TSA numbers went up most of the summer. They're now stalled at a plateau. However, people are tired of being stuck inside the house.
Covid numbers have been in a decline. OK, Europe's increased a bit but overall things are slowly getting better. We'll see how things go this winter, but if it's not a huge increase, I could see where a lot of pent up demand for travel takes place next summer.

But yes, I could just be an Eeyore and point out how bad Covid is. If I were 70+, I'd be more concerned about Covid but it's already run through our house without any funerals or overnight hospital stays.
