TSA plagued by staff shortages as more airports see uptick in travel

As more Americans fly again, we're seeing long lines at security checkpoints and the TSA may not have enough staff to keep up. 

According to a TSA memo obtained by the Washington Post, 235 airports are currently under-staffed, including some of the nation's busiest, like Boston Logan, Denver International and Washington Dulles. Some airports are short as many as 100 TSA officers. In some cases, passengers have been asked to arrive three hours early to ensure they make their flights.
