I dont miss flying much at all
I know we are all flying and travel enthusiasts at heart, but I find myself surprised at how little I miss flying. I am (at least pre-Covid) a 2 million miler on CX, PPS on SQ, and Platinum on VN: was on a plane 2-4 times a week, most weeks. I most especially love all the extra time I now have by not traveling; even a short hop like SGN to SIN or SGN to HKG takes 5 - 6 hours door to door, one way. I do miss the excitement of traveling to a new location or an old favorite that I don't visit frequently, but unfortunately 95% of my flights were not of this type.
In fact, I hope to maintain a much less intense travel profile when the world goes back to some level of normal.
