The economic damage caused by the pandemic is somewhat unusual in that it seems to be disproportionately affecting lower- and middle-income families, especially those working in the service and hospitality sector. Higher-income people (and those that can afford to travel) seem to be less affected. At least for now. This may significantly influence how fast recreational travel comes back. If I had to guess, I'd say that leisure travel will be back to somewhat normal levels in two years.
I have been working as a airline pilot since 2001. The decade from about 2002 to about 2011 was an extremely rough time for airline employees. Statistically, the airline industry as a whole lost nearly 25% of its workforce during this decade. Not just pilots, but rampers, mechanics, flight attendants, and customer service agents. Improved automation may have contributed to some of this decline, but the majority of the staffing reductions were due to outside economic forces.
