In 2022, we are finally seeing a resurgence in worldwide travel since the beginning of the COVID-19 pandemic. The TSA has screened more passengers this year than during the past two years combined, but we have still yet to return to pre-pandemic passenger levels. Despite this, we see significant delays, cancellations, and other disruptions. This is worrying for both passengers and airlines alike as passenger numbers continue to rise and put further pressure on short-staffed airlines and airports.
