Woo boy. I travel a crazy amount for work (academic researcher). I'm just going to count capital cities. Many of these have been less than 24 hour visits (while traveling to somewhere else in the country), some have been week-long holidays/conferences: Copenhagen London Geneva Warsaw Berlin Istanbul Jerusalem Riga Helsinki Budapest Beijing Taipei Paris Madrid Tokyo I'm sure I'm forgetting some. Honestly, as selfish as it is, I very much enjoy the lack of air travel at the moment due to the pandemic. I hate flying, but it's a necessary and important part of my career to do so normally.
