$XSPA The next thing is costumer volume. XSpaCheck's current capacity at JFK is 500 tests per day, but I don't know if it can use up to that maximum capacity each day. Another factor is whether relevant staff at the airport are required to have a second or even a third test to be confirmed as negative. For the pre-COVID-19 era, I have no idea what average volume of one airport spa store is like, but I doubt it could achieve 500 - I would say even a number of 100 would be very satisfactory for them. Of course prior to COVID-19 they had multiple (>30) locations open, and now they just got JFK for the testing. To be continued.
